Okay, think about this. It makes a lot of sense really, why reward CTs for playing and not reward Ts? To be fair, the job of a CT can be harder usually because there are less CTs than Ts, but maybe that's why having a high play time as CT could be more respected then having a high play time as a T. Maybe the CT ranks are easier to acquire than these ranks for Ts, making it harder to get the play time ranks as a T. Although there are already several ranks for Ts based on kills, which is why CTs have these ranks in the first place as it is to discourage freekilling, maybe instead have the rank displayed next to the users name, similar to the CT rank system. I doubt this is ever gonna happen, but it would be pretty awesome and I think it would be a welcome addition.
