Don't remove mana potions.
Leave mana sustain in for the mana hungry champs. I shouldn't need to use most of my starting gold to buy a flask worth 180 mana (2 abilities dafuk is this) if i'm a mage and I am trying to output as much damage as possible. I was hoping that since you removed these, all mages would receive a mana regen buff. But no, it is still way too slow to matter at a lot of points. Mobility creeps and phys are getting literally all the buffs this season, which is strange because they were doing alright.
Btw, permanent grievous wounds? Return of Executioners Calling, now with 400% more toxicity?? The fuck is this? Was any thought put towards Morellonomicon or are marksmen just going to shit on mages all season long?
Alternatively you can rename this game to League of Fighters, or League of Fuck Skillshots
