I definitely agree with MuzakMaker (hope I'm not putting words in your mouth) that it seems weird that the opponents in the higher rounds are so variable in difficulty. I would like to see more consistency there.
No worries. We're in agreement. Long gone are the days where the Round had any firm rules on the difficulty. I've seen awakenings as low as D and that next run I won't get any until SS and by that point it's max awakened meta toons with meta talismans.
