So I'm going to assume that Bomb should always be used as a multi-unite/support skill as opposed to being your main means of attack. I'm not finding as much use for it as I hoped I would.
Oh, and how do you deal with spike attacks etc that go through your Guts? I bought the upgrade that boosts it by giving spiky protectors but I find it only works on certain attacks. I had to outright dodge a few unites that Vorkken did against me cause I couldn't possibly reflect them.
Wonder Spring with Hero Time. @Bomb: Yep, use it as a support skill / begin yout attack with one.
While playing i had constantly the thought of Kamiya brainstorming with his team what crazy shit they could implement if there would be no limits whatsoever.
In the end they took everything.
