Guild Wars 2

I never used anything but full zerker for PVE and dungeons so far. But now at medium level fractals I’ve seen obviously defensive warriors to fare the same or better than the usual full zerker dps.
Also, in some groups one just needs a spare armor.
So what to get? PVT? Knight?
And what will they nerf? Only zerker set, or will there be some, say, crit cap, effectivelly nerfing any armor with +crit stats?

You shouldn’t need a backup set. Its just L2Dodge, you won’t notice effect of any toughness at this level.

At the highest level fractals not available yet, 1 or 2 Knights pieces will make regular attacks a 2 shot though, but that isn’t out yet, so still not needed.
