I didn't use the dot-based BE build that was broken and only needed to do some minor adjustments to my build.
BE crits are now at ~200k dmg but when I tested it, the first elite got 2-3 hits and then the damage drops to 1-2k per crit.
Tested it on other mobs and maps, still the same. Then I reseted all my passives and modifiers, still the same.
While the dmg without any points spent are at ~ 45k, champions only get 1-2k too after 2-3 hits.
I suppose, by fixing the aligment+ dmg of BE you somehow bugged the skill, now when BE puts an ailment on the target -> some hits are the actual dmg, further hits only do the dot dmg?
I dont wear any unique with special affixes so this seems to be a skill bug,
