What about just accepting that you're wrong? I mean, nobody on this earth is always right. there are a lot of people who say the same: that you're a tourney 'tard and at the same time a n00bish player. and with a lot of I mean the whole KRR. so why not thinking about what we want to say? and you must be able to care criticism if you call yourself a pro. Everybody who shows their "skillz" all around the world must be able to care criticism. AND I WON'T FIGHT YOU NOW TO SEE WHETHER I'M WRONG OR NOT BECAUSE THIS KIND OF DECISION IS GAY.
Also, there's no direct limit of improving your skills, except the human limits. And don't tell me you reached the human limits - Spamming the same move over and over (EXCUSE ME, you just OVERUSE IT) isn't even on half of the human limit scale. It's just like thinking "uh I'm bored so I could spam (UH NO, OVERUSE) the same move and eat a cookie in same time..." I just want to say: there's everywhere a way to improve your skills. Go to training mode and blow up some lvl 1 CPU's - the typical human reaction: you get so proud on yourself and your rampage on these loosy CPUs that you automatically will try to do everything more elegant and cooler. and therefore you will automatically use more moves and will try different ways and you'll take the most deathly one that also works on your CPU-enemies on highest level in VS-Mode. just a hint how you could change your style or even getting a style. (though you won't take it, that's what I'm prognosticating.)
