Hammer build for WvW
I suggest the Boon duration one for starters, and you can then try others, or mix around what you like. I personally run the lyssa runes because of the extreme bursts, but its up to you. Hope it helps =D
Instead of Endure Pain, invest more into Defense to get Shield Master. 3 seconds of Blocking on a 24 second cooldown is hard to beat. Take Signet of Stamina for faster endurance regeneration (more dodges) and remove all conditions on a 36 second cooldown.
That WvW build has some serious issues against conditions and damage avoidance. Luckly your mobility is fine with the main hand sword.
