Hunter Solo - Durendil vs Gnarlroot
He doesn't seem to have a berserk timer. Or at least it's extremely long.
I'm missing about 20% dps for Igira though, so I guess I'll continue soloing amidrassil in TWW.
In phase 1, the small adds deal a massive amount of damage with their DoT. I used defensives if I got the debuff, and turtle on the second set of adds.
In phase 2, boss deals increasing damage, so I had to use defensives too.
