Well 1 because you haven't provided any sort of proof that R9 is overpowered, you just keep saying it without any sort of reasoning as to why. And 2 if you play 'professionally' why are you complaining, don't you have R9 as well? You'd think a 'professional' who's played '1000's of hours' would pick up the card he deems to be 'the most overpowered card in the game'.
Personally, I highly doubt you're a pro. I play in Div 1 and don't find R9 to be a problem to deal with, its the player not the card. I think more than likely you're a middle division player, either Div 6/5/4, that keeps getting beaten in cup type and competitive modes. I don't think R9 is the issue, I think your defending is.
