So why the **** does it matter then? If you hand their ass to them, then why should it bother you? In my opinion, it shouldn't. And sure, beam spamming does get annoying, but usually, the people who do it have no skill what so ever, so what else should they do? Beams are in the game. There are Dragon Ball Z games like Budokai Tenkaichi, where beams are annoying and cheap as hell, but do we complain to Atari to get rid of it? No, we deal with it.
Who says we should go by what you say, just so you'll still play the game? Hell, quit the game. No one gives a ****. Why would it matter if someone good at the game stopped playing? It wouldn't. You're just some random person who plays it. It's not like you're something special and everyone else isn't.
That isn't the case. If you didn't notice, Cell is better than Goku and Vegeta. Sometimes, someone who is better than the other person, will still lose sometimes, just because that other person uses Cell, and they use Goku or Vegeta. In my opinion, for matches, you should only be allowed to use Goku and Vegeta, because Cell is still better than both of them. I know it's not by much, but it's enough to win a match. I agree with you though, that Buu is cheap, and that they should degrade him for the next version, but I don't think it's a problem if new people use him in a public server. Now if it's match, hell no, Buu is too cheap. I think publicly, Buu is fine, just not for matches.
