I am a W/Mo (hahah

I use the build on pvx wiki, the triple chop farmer.
I modified it a lil myself because i don't have nightfall so i only have 2 attack skills...Now, sometimes when i go to the cave to farm them, its fine...
But every other run i go do, i get my ass kicked...
I do my attacks (triple chop) and it gets interrupted by the damn trolls...so now its on a 20 second cooldown and i have no way to heal...anyone else have a problem with the trolls interrupting? they use "Disruption Chop"
