Utility - The Third Power
With the Season 4 changes and the way Riot attempted to build Support kits into having the utility of their abilities scale higher with more AP/tankyness/etc. alot of individuals were nervous about high abuse cases where maybe a Janna could give an ADC 600 Attack Damage or the Lulu we have seen as of late in the LCS, even Soraka is making an appearance now. My answer to these concerns and end-all solution for this entire problem is this. Why doesn't Riot make Utility a stat? Change all supports ratios to scale off of Utility, make a whole line of Support items that give Utility points the same way Ability Power and Attack damage are given and make Supports scale off of those. Utility points do not necessarily have to be a damage stat but can result in better heals, better speed buffs/debuffs, better silences/stuns,etc. By making Utility a stat and creating a new line of items with Utility as a stat, you don't have to tone down Supports ratios or nerf AP items due to a Support abusing a utility stat with Ability power. These utility points can be placed onto Tanky items, Harrass items, Power items, Utility items, etc. and they cannot be abused by other lanes or classes because those champions do NOT scale off of the utility points that make the items worthwhile.
The perks of making Utility a stat:
It solves the current problem of Support characters being used in carry roles to gain a high amount of utility along with decent amounts of damage.
It saves tank items and AP items from being nerfed or altered due to any abuse situation brought about by a support character.
It adds more item variety for Support characters and players specifically.
