A perfect world thief has the highest DPS in the game – 25/30/10/0/5 to hit max DPS on a CnD > BS > 1,1,1 > repeat. Steals for Mug damage during CnD triggers and to bolster your init if your crit gain slacks. Someone else gives you Fury/Might. Target is a rock.
Unfortunately ANet built Thief with CRAP base damage. You have to go full glass cannon to bring comparable DPS to the table. SotG suggested they will look at thief base damage, and I hope they do – I’m tired of having no choice but to play a 25/30/x/x/x or 10/30/30/0/0 to be able to kill anything.
Unfortunately this is not 90% of the bosses in GW2, so here’s my opinion of weapon sets:
-D/D = if you’re a master twitch dodger, this can be a solid combo in PvE, but only on single targets. Though being able to 2-shot trash means that doesn’t really matter.
-D/P = Much more versatile bringing interrupts, blinds and mobility while keeping the burst. Top dog for PvP and blinds are OP in non-boss PvE.
-P/P = Your desperado look. Get the hat, and look cool. You get the Pistol skills without the mobility or stealth (which gives access to the only real Pistol attack that’s worth it). The only reason to ever use this is for things you can’t fight melee range effectively as SB sucks at range and the rest takes melee for DPS.
-P/D = It’s like having P/P unload, but at the cost of 1 more init, you get to do several K more damage and a bunch of bleeds much faster all the while gaining two mobility moves.
-S/D = This is your sustained DPS weapon. Auto attack DPS is very respectable, #2 is epic mobility on top of a condition remover, and #3 is a dodge, hard hit, and boon strip. I’d say this is more PvP as you generally could care less about boon stripping in PvE, but with the update adding boon steal, there could be points this is awesome.
-S/P = I find this to be a useful PvE weapon. You just own the face of trash mobs with BP and autos. Add in a stun and an interrupt, and you now also have great control.
-SB = This is actually a horrible DPS weapon, but the fact that it has nothing but AoE and Mobility, is the linchpin to taking on any amount of PvE trash. Drop gas on a group and auto attack to get a quick poison stack, and once they get close, kite and CB spam them. It’s not even fair to trash mobs as shotgunning Cluster Bombs at melee range actually becomes good DPS and can wipe groups of any size.
Really, pick what works for you since as I don’t see there being a ‘bad’ choice with the exception of P/P. If my dreams come true and they turn P/P into a highest range DPS weaponset that it should be, then it would be complete playstyle.
Enjoy it though – I’ve seen many lame complaints of Thief being weak in PvE, and that’s all bonk. I’ve had no trouble with ANY open world content or dungeons – it just happens to be “why bring a thief” to a dungeon when a Warrior provides better DPS (why must you suck Pistols?) and better support (thief class support is blinds and CC, and bosses are immune to both. Yay!)
