Removal of mana potions.
With so many changes on the way, trying to make an accurate assessment of exactly how all of these will interact can be pretty difficult. I did feel that one thing stood out a bit and that is the removal of mana pots.
My thought is this going to be a huge indirect buff to Energy/Resourceless champs. I mean lets face it. To keep up with these champs you normally need a few mana pots on top of a Chalice early. Are traditionally mana hungry champions going to be compensated with Mana cost reduction or some other way to keep pace with these champs?
