It isn't that he was bad, I just always thought that he was rather awkward to play. I don't like his Side-B, too stationary, and I don't like how you are so fragile during his recovery. Of course it's a matter of preferences depending on what playstyles you like to play, but I wasn't a big fan of how he played in Brawl, he does however look a lot better in SSB4 imo, definitely looks like I'll be able to enjoy him with some new gained mobility with his Side-B, and the Up-B looks more like my style.
