Seriously, mana pots are the only reason why I'm not going oom after casting three spells in lane. Seriously, with the removal of them, it will be hell for AP Ezreal to get to his late game. And mana regeneration itemization isn't even that good right now.
They are going to adjust many champions' mana regen at early levels in order to compensate for this: http://www.surrenderat20.net/2015/10/preseason-2016-crests-horizon.html
I think youre freaking out a bit much. It will mean he has to play more sparingly with it and smarter, but I think Ezreal would still do just fine. But Im not as well versed with Ezreal as most Ezreal players :P
Because only Ezreal would suffer from it.
