Set a limit on heavy healers in ARAM
One of the fun things about aram is the unpredictability of the team comps. it's also one of the annoying things about it. And sometimes, it's downright ANTIFUN. particularly when we talk about healing. It's difficult enough to overcome a sona/soraka/janna powered team, but what happens when the enemy has sona, soraka AND a nice bit of healing from fiora ult. You basically autolose. particularly because of sorakas synergy with other healers (heal soraka and she can heal even more). And not autolose in a fun way, just the "hey you cant actually kill us no matter what" kind of way. There should be a limit to how many of the champs a team can roll. Even if that makes it "not random"
