It's sad that you're quitting since you're one of the biggest factions and it's a big loss for C-rpg/strat.
I'm just not sure whether I will miss you or not. There is no biasy in the bans, seriously. You had it coming after you've been cheating for soooo long, honestly since I started playing 1,5 year ago one of the first thing a widespread of random players told me were that Greys were a cheating clan. A label well earned -.- or were people wrong?
The fact that you're so closed associated with cheating made every battle in strat against you have a bitter taste to it, even if the battle were fun and there maybe were no cheating involved in the aspects which led to the battle, you could NEVER be sure. You deserve these bans for breaking the rules, and then leaving the game screaming "UNFAIR" when you get punished for playing unfairly, well... haha. So now that cheating are being dealt with and the effects of cheating cancelled out, you're leaving the game? To be completely honest that decision doesnt surprises me. Those of you that were cheating, all I will say to you is that you were never good for this game, or at this game.
Some other minor aspects of you will be missed though, along with some of your players.
