Ok so im planning on getting my rogue to 60 and keeping her there eternally so I can molest horde whenever I feel like it (since 60 PVP is still the best IMO). So my plan is to get full Gmarshals +the deathblow goggles when i can get the nether (2.4 non-soulbound ftw!) and maybe a few pieces from Ramps/BF assuming i dont go over the level cap. Spec wise im planning to go Hemo sub and get shadowstep (yeah yeah i know but its just for fun :) ) so i can bounce around on those hordies.
My question is should i go for Gmarshal Longsword/quickblade and either mongoose em or +15 agi both, or should i go for a dagger/sword combo and a different enchant type? Just looking for w/e would deliver the biggest numbers and/or perhaps most viability.
PS: May also consider mace spec, not sure how good it is since ive never played a mace rogue.
