I'm trying to figure out what gear is going to be best for a rogue as well as where to get it and I'm not seeing much in the way of documentation on this.

Anyone have a link to a wiki or something? Crafted gear, raided gear, sets, etc?

Basically just Tier 2 stuff/Loot from Castle Never and Seal of the Drake

pvp is good.
t1 is better.
t2 is even beter.
t3 is best.

crafted is good depending onw hich pieces.

So basically just level to 60 without worrying about gear (use what you find) and then at 60 focus on end game gear? Can any of this be gotten in the AH or do you have to raid for the t-1-2-3 gear?

you can get pretty much everything from the AH
