I also did not realize that the rage would be increased with a heavy attack and will test that out. I found the cheerleader cartwheels to be A LOT less annoying once I started remembering to use ranged fire.
Oh, one last thing, the animations for the Finisher Hers are superb and I LOVE them, but I strongly believe that they should grant invincibility. They require full rage, rage does not get retained between lives, and only target one enemy. So, it's not like invincibility during would make it OP and NOTHING is more frustrating than finally landing it on an enemy you haven't used it on yet, only to be interrupted 0.3 seconds in by a projectile, because you are a sitting duck whenever there are other enemies around.
