Truthfully I don't counter-pick, but as a tourney player I understand the reason for it. Part of winning the game is learning to exploit match-ups. However there is the matter of the Hidden Select feature which lets some players avoid it...
I use multiple characters, so at times when I take my time deciding who to be, they think I'm counter-picking them, which I'm not. Actually I kinda hope they'll pick a character that has an advantage over mine, because it allows me to challenge myself towards improving on the negative match-ups. Like I once told SHORYUKEN, I'm of the belief that match-ups alone don't decide a game, even though they play a role. It isn't the character alone that wins a fight, rather it's the player who uses him/her. An advantage is one thing, but it takes more than that to win a match.
I know there are some who may disagree with this, so feel free to state your thoughts. Nevertheless, my opinion is my own until it changes. Don't get me wrong: I am a player with the "play-to-win" mentality, just that I believe winning stretches beyond more than just using some high-tier characters.
