But what if we made it so that Roll had a bigger double jump, didn't take extra damage, could autofire in most cardinal directions by holding the shoot button, and had a faster dash? And in exchange, her dash wouldn't fit into 1 tile high gaps?

In all seriousness though, I find it interesting that Rock is arguably slightly better in the first 1-2 stages because the charged buster is very powerful when you don't have weapons yet. He needs some sort of edge on actually using the weapons or the ability to charge them for the balance to be remotely even between them.
