I think it would be really cool if draft pick normals were based more significantly on player skill and Elo, whereas blind pick normals were much more loosely chosen. As a ~1950 player, I usually get matched up with 1600+ players trying their hardest in blind pick games when in reality I just want to mess around with some item builds and champions. There is currently zero option in this game to just have fun with "troll" builds, roaming, strange summoner spells, etc. without ruining the experience of other people. For example, even if I queue with 5 people, and we all run promote and surge, we still usually win. The other team leaves the game feeling awful and unskilled because we were blatantly trolling and still won. On the same token, if I am only with a few friends, and we want to do something fun (AD Sona, support Ashe or something along those lines) and have a bad game, we will most likely get reported by our teammates for trolling even though we were 3/0 in lane and just weren't able to carry hard enough based on the comp.
TL;DR -- Create a mode for less serious, more fun games. Or turn blind pick normals into this. I don't play normal games to tryhard, UNLESS I am doing draft pick.
