Been following that build, and it's going alright so far. It's just Fire Attunement is very, very unreliable at igniting the gas clouds from skeletal snipers. Any easy ways I can fix this? Just started act3 lvl 33.

Edit: Bosses are sort of fine, it's all the pack mobs in the map where it falls short.

Thanks
