Ivern's doing okay but still needs a little something, I think?
Brushmaker should have some sort of lingering 2 second buff effect while standing in or when you leave the bush. it could be a small ar/mr buff, like 3-5. Maybe you move a little faster in brush, like that old mastery that let you move faster in the river and the brush. maybe Ivern just passively moves through brush faster by himself? That would be a unique buff, that, uh, really can't see how that would be OP in any circumstance, and it would give Ivern the little shot in the arm he needs without becoming overtuned. Heck, you could even gasp program Daisy so she isn't a complete moron.
Maybe she could even be able to attack inhibitors!!!! I know, crazy idea. I'm a madman, but....perhaps its possible @_@ for a champion that's existed for over a year, for his ult to be able to attack an inhibitor.
