Gold income and game speed
So just a thought based off of first impressions, the gold system feels a little constricting as far as how much you can do in the early game goes. I think it would be interesting if you got a gold reward for say damaging an enemy turret/node/etc. Currently when you damage (or maybe it's kill, I don't quite remember) a turret, gems pop off of it as reward, I think it'd be neat if instead of gems you gained a static amount of gold. Not sure whether it would make more sense to reward the individual damaging the turret with gold, or to have it be a team gold reward, either way I think it could make for more interesting game play as it would encourage quicker pushing towards nexus and a lot of interesting team play
