Ran some super barrier stacking to test Maze. Didn't pose a significant problem with a sufficiently redundant build, thank you very much for the change.
Although it made me realise 'Lonely Witch?' should work slightly different. Not so much for balance, as more the fact that with my random damage based team combats against them took 10 minutes every time. My suggestion would be to reduce damage by a random amount between 0 and 10.
