what traits do you want?
You move 25% faster. The duration of incoming movement-impairing conditions is reduced by 25%. (Cripple. Chilled, Immobilize)
Oh wait
Full zerker will never go away unless they design fights specifically against it like mobs immune to crit, mobs that take reduced melee damage and increased condition damage, etc. On normal encounters berserker will always be the default best stat choice because more damage = dead mob in the least amount of time.
