GUYS RIOT IS REMOVING MANA POTS!!
Seriously wtf WHY?!
"As for sustain items: we first started with health and mana potions. Health pots are going up in price to better position them as a purchase for those who just need some sustain to get them past the early game. Any form of long-term sustain we folded into the refillable potions (and their subsequent upgrades) to really solidify their identity (because before, it was… flask and potions to be a ‘sustain’ build). Mana potions, on the other hand, are being removed. Our decision to remove mana pots goes along the same philosophy as starting items. 100 mana tends to benefit certain types of champions over others (with mana costs being balanced against individual champion kits) and can wildly shift from being a mediocre purchase to a very cost-efficient one. By removing mana pots, we can better balance champion ability costs with the mana regeneration stat while also streamlining the ‘sustain game’ of League."
Hmmmmmm
