Support
For years the "support" characters have been broken in one way or another. Either you have them ok as a support but completely overpowered as a solo laner (soraka, lulu, etc) or you have their abilities scaling so poorly that it doesn't even feel good playing them as a support because they don't seem to scale at all. Does anyone else feel like perhaps they should be scaling off of a different stat than AP? Maybe they could scale their abilities off of something else? GP5 seems the obvious choice but that doesn't seem quite right either. What if a new stat were added to existing support items for their abilities to scale off of instead? It could work pretty much the same way as AP, but the items that it were available on could be balanced specifically for the support position. Maybe some abilities still scale off of AP for them, such as their damage output spells, but say heals scaled off of the new stat instead, so that those that still want to play lulu in the top lane could do so, but their shields aren't going to soak up as much as a support lulus would, and their ult will not heal for as much either. I know the chances of this happening are slim to none. This type of thing would take soooo much work to basically rebalance the entire game and item system, but I think it's a kind of cool idea and wanted to see if the community thought so also.
but it really isn't used much...
