I'm terribly confused with Warrior traits
YOLO … Yea, right until you respawn
I don’t have much experience in Spvp but in WvW it really depends what your planning on doing. Are you going to roam around or follow the zerg. I find condition removal to be really beneficial. Shake it off and/or the condition removal signet. Lots of people like endure pain for the few secs of invulnerability but I find the CD to be a bit long.
Try looking at the warrior forum.
