ah i see what you're saying pocky, no allow me to elaborate on my train of thought.
CP are cp because as you said they have a wierd or random element, and as the better player, you probably want to stick to neutrals to minimize the chance of wierd elements interferrign with your expected win. But, if ou are the 'better" players, then you shouldnt even need to cp right? you should just 2-0 and 3-0 everyone. But if you ever do need to CP, its because you lost a match, possibly on a gay cp that your opponent has thrown out.
now, what im saying is, it is possible to have mastery of a stage such that you use it, not as simply a cp, but an auto win.
to illustrate, i'll use this scenario:
lets say you and your opponent are both arbitraily skilled on a scale of 1 - 10 and you are a 7 and your opponent is a 6.
first game on a neutral, you win (barely).
second game, your opponent cp a gay stage and because of this, his arbitray skill points rise from 6 to 8 because of the stage and yours stays the same, or even decreases possibly. you lose.
no, still speaking hypotheticaly with arbitray skill points, you have to CP for the 3rd game and you have two choices:
you could go to a neutral where in theory you have the advantage because you are slightly better, but he could still win. but what if you had a cp in your back pocket, a stage you're so comfortable on, it boosts your "betterness" than your opponent, to an almost unbeatable level. you go from a 7 to a 9, and your opponent either stays at a 6, or even decreases.
now, you could either fight on a nuetral at 7 vs 6, or 9 vs 6 if you have a strong counterpick, personally, i'd go with the latter.
I hope this example wasnt completely stupid and you guys are able to follow this. Thats just how i see the situation and obviously everyone has varying opinions.
in such a jaded game though, im looking for anything i can get over my opponents because everyone these days are really good and i've been been toying with the idea learning the gay stages and trying new things
