Team Builder Roles.
You have a role system, and it's nice and all, but I don't like the fact that you made specific champions have specific roles. If I wanted to play Vel'Koz support, I don't think I should have to wait long amounts of time for it, if that approximation timer even means anything. But! The main problem I have is this, why does no one ever bother to put in the damn roles for bot lane? You need an ADC, and a Support, yet I constantly find people who've been in the queue for 20 minutes, and haven't put roles into the bot lane, and are waiting on a support, yet only get ADCs. Then the group leader whines about it. Well yeah! You were too damn lazy to put in the roles for bot, so now you have to sit for forever through the various amounts of people who want to be ADC! Which brings me to my next point. Can you have the roles for ADC and Support be automatically filled when you click find players without designating anything? That way if you're too lazy to put the roles for bot in, the game will do it for you? SO I DON'T HAVE TO BE EZREAL SUPPORT, BECAUSE I VOLUNTEERED, THEN GET YELLED AT BY MY ENTIRE TEAM, WHEN AT 20 MINUTES, WE'RE DOWN BY 30 KILLS?!?!!?!? I mean really, if at 9 minutes, we're down by 6 kills, and we haven't gotten a single one, we're going to lose.
