where are warriors?
easy to answer actually (at least for zerg fights)…
Berserker brings much more to the table than vanilla warrior. Your burst skill is suddenly useful again since the stun from the normal Hammer F1 wont matter since the stability changes. The Beserk Mode Hammer F1 gives you an aoe root and still has a daze in case someone doenst have stability. You also gain more dmg for free from the beserker traitline. You still can take discipline and defense as a berserker so you dont loose much from taking beserker.
in case of roaming… beserker is mostly better than the other traitlines since most of the beserk mode burst skills are much better then the normal ones (especially greatsword for example)
in terms of big fights exactly what the Asura said, right now i’ve been using GS/Ham build with berserker traitline and Soldiers gear + Zerker weapons and accessories, with Banner as the elite (ALWAYS USE BANNER IN BLOBS) in wvw blobs and its worked wonders, great damage output while still having pretty much 11 seconds of invincibility (Endure Pain trait, Endure pain as utility and Defiance stance as heal) and to add to that its super fun, you feel like a complete beast wrecking havoc in the frontline of blobs.
