I would, a billion times over, rather wait longer than be forced to play support. There are enough hardcore trolls and feeders in bronze that I have to carry without being severely disadvantaged by being put into a support position. Also losing a ranked game where I was forced to play support just ruins my whole day. If Riot wants people to play support, why not improve the effect that the position has on the game (dramatically) so people want to play it rather than forcing people to play it?
Also what do people do when they're forced to play support in bronze? Should I just try to play a carry out of the support position, since traditional supporting won't do anything at all in bronze?
