Two things I hate are evade champs and mix master. Put them together and it's just LOL bad for me. But I've been super lucky to get gold or t4b on that path most of the time so I just skip it.
Civil Warrior is the obnoxious one for me. He never does much damage to me, but the combination of his continuously increasing amount of armor buffs and weaknesses building makes it feel so much longer than it needs to be. Dr. Strange is also a pain cause of the power gain
Wow, I feel dumb now. Didn’t see any civil warrior posts 😂. I always bring doom 5* dupe rank 5, rank 3 6* warlock , rank 5 5* AA. Can’t seem to get him down fast. Takes FOREVER!!!!! Can’t bleed can’t poison, can’t power drain, I CAN do 50 damage though 😂
Jabari Panther. Man, that Cleanse mechanic coupled with the aggressive AI is so hard to deal with.Also Doctor Strange. He never seems to want to throw his Specials.
