Way to take an idea out of context. I wasn't saying frequent posting means a better character, but being inactive for two months then turning up and saying that your character is better than everyone else kind of misses the point. And no, posting every day won't make you better than everyone else: someone who posts 20 times a month won't automatically have a better fighter than someone who posts 10 times a month, you've actually had to have been in fights or do training or whatever to justify it. I'm willing to go for an idea that people choose how strong they're getting and the GM can intervene if they think one person is running away with it. We've done this before in an RPG way before you joined the board and it worked out fine.
I'm not sure where you got this idea that Frieza was stronger than Goku; I was under the impression that SSJ Goku was stronger than 100% Frieza. At worst, Goku merely struggled when Frieza went all out, but he definitely wasn't losing.
