You can get to Boralus with a bug/glitch even if you don’t have bfa on your account and you are able to learn https://www.wowhead.com/item=159829/belt-enchant-miniaturized-plasma-shield which is a bis (because it’s the only one ) belt enchant. I have not so geared 210 rogue and it gives 5k absorb shield(it scales so it would be 6-7k for fully geared toon I believe). You can also farm this trinket ILVL 210 https://www.wowhead.com/item=162966/dread-aspirants-badge&bonus=4990 from this crates https://www.wowhead.com/object=290135/war-supply-chest. On horde you can only get trinket. Didn’t see this info anywhere so I thought why not post it. To get to Boralus you just board the boat and once it moves you log off and log in after 15 seconds(there was a vid from f2p pal I forgot his name but it was him who discovered it I believe) Edit:you can learn any other profession there too, with exception of herbalism(weird). But I didn’t find anything useful for pvp other than this belt enchant(which costed me around 12k in reagents so mind that too)

If you do a lot of WPvP, it's quite useful to have - no matter how careful you are, you will get dismounted by enemies. Tailoring also allows you to use https://www.wowhead.com/item=41509/frostweave-net, which can be quite useful to escape or prevent the enemy from doing so.
