Guild Wars 2

As the title says, these questions are probably self evident and I am just missing something but a google and forum search still left me with some questions.
I just turned 80 today so please go easy on me when I ask these :P
Are any stats related to condition damage, other than the condition damage stat(ie. power?)
Are terrormancers a viable build in WvW?
How am I best suited to help my party in PvE(powermancer, condimancer…etc?)
What traits should I be avoiding, in regards to them being bugged?

Thanks in advance

Condition duration, tho you mostly get it from non gear sources and indirectly precision, because a lot of conditions have on crit triggers (like barbed precision and sigil of torment).
Terrormancers are viable in everything but dungeons (they kinda work in most fractals, tho only for nub groups which need breathing time vs mobs, fearing aint good when organized).
Best support is well necro with protection, best suited is to just bloody slaughter your way trough or if you do fractals a lot, be the kite/aggro guy (since well of darkness, DS, Lich/plague let you help the team trough more annoying situations)

Overall recommended for pve would be the DS DPS (tho spojs red stickied build works way better for only pugging) http://gw2skills.net/editor/?fRAQNAW3djc00SbRN+0whbiahC6EIAmho6AqbjzoaB-ThRBwAX3fU+dT9HU6G0cRAA8EAMrEMAACATciTciTciBA-e
