For a rogue, you should get (for a basic setup)
fang set: boots, gloves, pants (+7 stam or Minor speed increase boots / +15 agi gloves / +16 armor kit)
Shoulders: Serpent Shoulders (pick these up while your running for your legs / boots in W.C
)
chest: defias (+4 all stats) or Tunic of Westfall (+4 all stats if your alliance)
belt: deviate scale belt ( N/A)
bracers: forest leather bracers (+9 stamina)
Alliance Rings: Seal of Wymn / Honor Reward
Alliance Neck: Honor Reward
Horde Rings: Seal of Sylvanas / Honor Reward
Horde Neck: Honor Reward
weapons: CB / CB for melee, Tail Spike / CB for stealthing and such... you can replace the tail spike with the honor reward weapon you get from the silver sents or wsg outriders.... UNLESS your HORDE, then I recommend getting the WINGBLADE, superior dps over the CB and even some stats to boot!
I personally I have like eight different CBs (since this twink is alliance) with different enchants just because I like having different setups.
Agi / Agi - i use this against rogues
Fiery / Fiery -i use this against hunters and lowbies when I'm bored
Fiery / Agi - For Fun, pretty useful against other rogues
Life Stealing / Agi - Same as fiery / agi
Crusader / Agi - Same as fiery / agi
Crusader / Crusader - Just for fun
all depends on what you like, I personally think that ANY dagger you get for ambushing should have +5 weapon damage on it.. +15 agi < +5 wep damage for DPS, even though you get a bonus of crit.
As stated before, you CAN wait until the next patch to turn off the exp (this is what I am doing with my current level 10 twink I have started ATM.) but, if you don't wanna wait and get your boots dirty and get a little practice in before 3.2 hits, thats great too
.
Hope this post helps man, good luck :3
