Riot really hates Yorick
First they update Shadow Isles lore and not update his and now they are removing mana pots. Yorick would walk into lane with a flask and three mana pots cause he basically trades mana for health. I guess Riot doesn't remember Yorick Mori.
a champ that even riot admits is op, gets a rework before a pretty decent Halloween theme based champ
. This would have been the prime time to roll out a good solid rework for him
