I don't want to be a dick, but showing off in a battle like that is not necesserily overpowered, it'd be different if I acted like this in a duel between players.
Sure I am overpowered when you make all the character's act like wimps, I mean for fucks's sake. I stop a spell and then this arrogant I am a God guy goes all like ;_; "Ah! No! Please stop hitting me, ah, my face!"
Our abilities pretty much only managed to erase eachother, but all the sudden it appears I am too powerful for him to handle, which makes him QQ
Nor was it me that slaughters armies.
