Let's face it, the AP side of the champion pool has the worst of it right now. Where as someone playing AD can buy a BT and call it a day, not to mention hexdrinker, AP champs have to fall back to weakly building up a zhonya's and not to mention still lose in trades because of sustain. It's a little overkill that AP champs now don't have something to solidly heal off of that isn't risky or won't benefit them later.
Should AP champs get something that allows better sustainability? And would something like this help out more with balancing out the champion pool?
