Hello,
I was noticing my Burn ability on my level 50+1 Brute that has the Superior Avalanche set slotted, seems to be missing quite a bit on the enemies surrounding him. I don't know if this is intended on this new patch or not, but I am seeing a lot of "miss" than I did in the previous patch. I am testing this out in AE (specifically map id 51577) , and it is a Fire/Fire Brute.
