I wish there was a way to speed games up!

I like urf for the one reason, pushing towers. In Urf a lot of people seem to get it. I will not help you get kills when killing matters very little. In Urf you have to kill to get to the turret but you can out play people with teleports and wards at an accelerated rate to so the game doesn't drag out. I wonder who decided that 20 minutes was the mark of a fast game and 40 minutes to an hour was dragging it out. Would it not be cool if the average game was 15 minutes, where the variance was 5 minutes? Games that went up to an hour were negligible anomalies, usually played by new people that were learning.

I know things are faster in ranked most of the time, but considering almost half of the community is bronze- silver will lump them in with normals and causal gamers. I wouldn't mind trolls and those that don't care, if it didn't steal an hour of time.

I don't want normal games to be crazy like URF. I just want a little speed. How can Riot get some pep in the step of Summoners rift?
