Guild Wars 2

Yes the build is still viable, however skip the berzerker parts for more Power, toughness & Vitality pieces. I also prefer Dolyak signet over Balanced stance since it gives 180 toughness Before you pop it.

For seconday sigil you either want Hydromancy (CC), Renewal (aoe heal), Energy (endurance, gives you an extra Dodge) or Accuracy (makes you crit more often, which is good with the flameblast, especially when you have lower critchance due to no zerker parts)

If you want to help your Group & stay alive while fighting a Zerg then this worker build is for you: http://intothemists.com/calc/?build=-s;4NKkN0_4NLVQ0;9;6TT9;417A18B3;0LBZ420;0CqNYCqNY;0kg0-wY90;1vV0X5Y8ZG4L5;9;9;9;9;9;9;84k3l
(accessories depends on whether you want dps or survivability)

If you only care about yourself & want to survive then go for this:

This is a good build, I use something very similar with just a few minor tweaks:

This build is not new in any way & can be improved a lot. I played something similar for a long while until I changed around to my latest build. Here I changed it into something better for you:

We have a nerf incoming to Healing Signet, which will probably be enough, howevere make it heal more when Active & you´ll see it used more like a healing skill.

Bow is getting a nerf already. Add in a cd on cleansing ire, say 15-20 secs & voila, no more OP warrior Hambow builds, it will open up for more different builds
