I did HUGE amounts of trolling with my Thief yesterday.
Dual Daggers + Shortbow.
Kept pulling people off of walls with my Scorpion Wire, used Poison Blast + Cluster Shot for Area Weakness on large groups. Tons of teleporting and stealthing around. Jumped into big groups, picking off one or two people, then stealthing/teleporting out.
I went an entire 30 minutes without dying or being downed and I got tons of kills.
Also put up a few arrow carts and held two bridges against a huge zerg with a much smaller group.
Awesome times,seriously.
This makes Thief sound so awesome.
But it was the last class I tried out during BWE3. I felt their damage was horrible compared to everyone else's and were way too squishy - in PvE. At around level 6 I quit trying, refusing to endure the pain of playing the class with the hope that it gets better.
Do they just shine more in PvP?
