EDIT: We probably won't see any significant changes except to new champs who are overpowered until the season 2 finals ends. Looking at Rengar and Syndra... yeah, probably won't see any significant changes soon. But then there should be a huge gutting of all the viable top-lane picks, which will likely include Riven, Yorick, Jax, Udyr, and Malphite. Then people will start taking AD Malz top lane to crush everyone in lane kind of how Yorick is used now and he'll get nerfed, too. So, season 3 bot lane in Dominion should support significantly more variety and a lot of the OP champs will get their early games hit. As long as the 0CS meta is being encouraged, though, supports and carries will continue to only be balanced (or not) by coincidence without some severe itemization changes or new mechanics letting you gimp one person's gold gain to increase another's.
