Thief Duo
Venom sharing can go both ways but lends toward power builds.
Also impractical levelling since it requires 60+.
Splitting gear wouldnt be bad if one was cond, other pow/pre. Though with both of you, cond would be rough on single to single mobs unless vet/champ – dies too quick.
Were very flexible, and by the time you have 10 in a tree you can respec free (w/book) and try another traitline.
Sword – control
Mh dagger – single target
Mh pistol – cond, single.
Oh dagger – kite utility, cnd
Oh pistol – melee mitigation, combo field, interrupt
Shortbow – mobile, cond/power mix, finisher(blast), poison ezmode.
If I always ran around with another Thief, I’d have one of us venomshare in PvP/WvW. Being able to share your stealth utilities etc. as well, and it just gets ridiculous.
Resident Thief
Both should use D/P.
That way, one guy can put down a black powder and both of you can heartseeker through it, effectively sharing stealth and saving so much initiative.
A solid duo would probably be D/P Direct Damage, and P/D Condition Damage.
D/P guy can get a lot of Shadow Arts to help the two of you stay alive, and P/D guy can get a lot of Deadly Arts to control and weaken the enemies.
With P/D guy taking a lot of Trickery, he can also apply boons to the two of you.
