Added substantial content to the Gameplay section. I will update other sections in the near future.
Warsong Gulch Tips And Tricks EPIC:
I have created a huge monstrosity of WSG tips that I use subconsciously and daily. This is a lengthy post, but I assure you there is plenty of information that players of all levels can get out of it. As I've mentioned, it is of substantial length, so don't over do it. Read a little bit at a time or whatever works for you.
Dark Jade Focusing Lens:
Not enough people are using these Focusing Lenses. They will shoot a beam directly through any terrain and /or obstacles and follow your target. Use this on EFC if you are standing near the end of your tunnel and you are unsure as to where he is exiting your base from. However, be warned as this will remove you from stealth and will also alert EFC as to your position and that you are on to him. This lens is best used to determine which way EFC is exiting from your base.
RangeDisplay:
This is a prime addon you need to get. It will show a range bracket for your target, your mouseover, and your focus. What this means is, you target EFC via Battleground Targets addon and immediately, it will tell you how far away you are from your target. For example it may say you are 20-25 yards from your target and then it may say your target is 25-30 yards away shortly after. If the distance is rapidly increasing, then you know you are not going going in his direction or that simply you are not nearly as fast as him. This addon is crucial for telling where EFC is. If you are within 60 yards, you can use your Focusing Lens.
Basic WSG Strategy
For the start of the game, you have 2 options. Either sit in your FR at the start or go down tunnel and try to assist with the mid fight. Chances are you'll be nearly useless in the mid fight as it is very well catered to ranged DPS, so your priority is sapping high profile targets on the opposing team which will hopefully result in your team gaining the upper hand. What I often do, is go out, sap the targets and then as soon as I have done my job, I'm already hunting down EFC and headed back to our flag room if I cannot cut him off at the start of the game. If the opposing team does not have a FC going for your flag, your job is now to hang around your healers and attempt to bust any rogues or ferals looking to take out your healers. If the opposing team has no FC, no rogues and no ferals, you can then see about aiding your team in focusing a healer or two, but don't get carried away. All you need to do is drop a few healers before your offense will naturally push the opposing team back. After you've dropped your targets, start heading back to your flag room to look for an incoming FC.
Your sole purpose is to return flags and aid in their returning. What this means is, you will not always be the one ambushing EFC and getting the return. Sometimes you need to be the guy laying down a sap on the healer and missing out on the return credit. As long as your team gets it, it's a win. Regardless, from the second an enemy flag carrier touches your flag to the second he is dead, your job is to be GLUED to him. Wherever he is, you should be and wherever he goes, you need to report in BG chat where he is. If 2 opposing rogues are playing correctly, neither rogue should ever see each other during a match as he will always be on your FC and you will always be on his FC. Your paths really shouldn't cross much at all.
With that in mind, you need to be aware of EFC's position at all times and his potential support. As soon as EFC is entering your base whatever you are in the middle of doing is now irrelevant. You are now to completely drop whatever you are doing, and do whatever you can to prevent EFC from leaving your base at all costs. You won't always be able to kill him, so perhaps chain sapping him is what you need to do. You also must tell your team where EFC is headed so your team can cut him off. The goal is to never let EFC cross mid. You don't want a game to get to the offense and defensive point and building stacks. You want to return the flag as soon as possible. However, sometimes this is not always possible, and perhaps you need to wait for 6 stacks to drop EFC. If this is the case, you need to be ready to open at 5 stacks and your offense needs to be in position as the 6th stack hits. You cannot waste time as the first team to assault EFC is almost always the victorious team.
Cross Sapping:
Cross sapping is one of the most game changing things a rogue can do. Cross sapping is when a rogue saps particularly troublesome opposition DPS in mid to allow your FC to cross mid successfully. Good targets for this would be Hunters looking to conc your FC, Druids mid casting roots on your FC, Mages looking to nova or otherwise snare your FC etc. It's removing your FCs biggest threat from mid which will help him cross.
Locking Down Healers:
How do you take down an EFC with over 4k HP and 5 DPS around him? You cut off his healers while your offense focuses down targets. You have 2 extremely useful abilities when it comes to taking healers out of the play. Sap, and Kick. What you should do, is find a healing caster who is the most effective healer on the opposing team. This is going to be your kick target. What you are then going to do, is find the second most effective healer on the opposing team. Your goal is to kick the most effective healer while having the second most effective healer sapped, while your support is focusing down their top desired target.
Based on the positioning, you may be able to sap secondary, open with an ambush on the EFC and then focus kick the primary healer. If the EFC is not close to the primary healer, your best bet is to simply sap secondary and then open on the primary healer while kicking immediately after opening in attempt to open and kick his mid heal.
If you are going against a team with only a Priest and a Shaman on D (as opposed to double priest, or double shaman, or double MW etc), throw out the most effective / least effective rule of thumb (within reason) and check this out. If you were to sap the Priest, the second he is free of CC, he will cast an instant absorb to mitigate burst which is extremely effective. Now if you sapped a Shaman instead, the instant he is free of CC, he is going to begin casting healing surge. If he casts Riptide instead, he has just wasted a global on a very ineffective heal and chances are his FC will be dead by the time he does get a Healing Surge off. With this in mind, your kick target will be priest and your sap target will be Shaman as a shaman is even more delayed in responding to burst than a priest. Every time you try this maneuver, you should expect your sapped target to trinket so be ready with a BE silence or a resap if he does not pick up combat.
Monitor Your Cool Downs and Consumables!
Cool downs and consumables create a higher level of gameplay. If you use your cool downs effectively you will have a higher rate of survival and success. Know what consumables you can use and when to use them. Do not go all out on consumables just to get dropped when you exit your graveyard. Be smart and conservative about using your consumables until the game is on the line. When fate of the game relies on one play, that is the play where you go all out on your cool downs and your consumables. Most of the time there is no need to waste your AGM on a random person. Unless that one person would be in the progress of leaving your flagroom with your flag and after a long battle you just need that extra cool down to ensure the returning of the flag promptly.
