@Riot - Will you please consider removing 4 player groups from the game entirely?
Now I'm mostly a solo player, but I can NEVER remember playing as the 5th man with a 4 group and having a plesent time of it.
Often the click mentality kicks in before thw game even starts; I've been threatened with a 4x report in champ select more then once if I don't give X position to Y person.
And once the game starts? God forbid you fall behind! Either alone or as a team! Because you will receive all of the blame! And thats just when they want to win! Not often but sometimes; you find yourself in the middle of some trolly experimental build that you will be expected to contribute too, and get bullied if you don't.
I'm firmly of the belief that if people can form a group of 4? They should be able to get a 5th.
Please consider this for the future.
