Guild Wars 2

So, just like many other warriors out there, I have a fully functioning zerker with lvl 80 exotic zerker gear, using the standard pve dps GS/Axe mace build. But now I find I get melted pretty quick in HoT content. How should I be changing up my build. This is the one im using right now. http://intothemists.com/guides/5899-solo_pve_warrior_build

I just took an Ascended Berserker Warrior build through all the HoT maps and beat the story. Main changes I made from pre-HoT:

• Slotting Hammer in place of Axe/Mace for controlling dangerous monsters (Shadowleapers/Bladedancers) and taking down break bars. If you’re doing a lot of this, trait Merciless Hammer over Heightened Focus.
• Slotting physical skills like Bull’s Charge and Rampage for additional control/breaking, trait Peak Performance over Restorative Strength.
• Using Omnomberry Ghosts for the 15% experience boost and health steal on crit.
