I think that's the only real advantage they got, so I wouldn't say it got a lot to say in SoloQ, except you can make them ban an OP champion to stop you from picking it, like when Jax was top prio ban before and I got on blue side I just didn't ban him because I pretty much knew they would burn a ban on him, or else face the fact that I could pick him and just be a split pushing God mid-late game.
I think normals got their own MMR? Nothing to do with Ranked MRR, so you can be placed with/against Diamond players if they lose a lot of Normal games because they troll/test new champs/builds. Not sure though.
