Mid Lane Ezreal and Runeglaive
Ezreal being able to benefit off of Runeglaive and Smite seems to be a bit on the overpowered side. It's not the item itself, (well kinda) but its the fact that his super low mana costs make him able to spam spells at the enemy without really having to feel the consequence of bad/careless aim. I'm actually completely fine with Runeglaive, but if there was some way to limit Ezreal's casting in the early/mid game, (make it like a Kog'Maw ultimate where each successive spell increases mana cost) then I think a lot of people will stop complaining about Ezreal's useage of Runeglaive.
What are your thoughts?
