Yeah I think I agree dashing to damage enemies would break the meta a bit. I wonder if there are other things you could do, maybe dashing into the ball makes it bounce like crazy... but somehow limit how often the player can do that? I'm not sure, but I think there's definitely scope to create some really fun and interesting interactions :D
Hmm, that's a pretty good idea actually. You can actually already dash at it for a more powerful kick but it's just not worth it since you can only dash orthogonally which limits its usefulness pretty severely. Having to dash at the ball to kick it was actually my initial idea but it didn't work out because of the same reason
Maybe it could get an AoE or something, I dunno? Or just become more bouncy as you said
