i dont understand why the rework for yorick takes so long, the fix is simple.
i played yorick support a lot back in season 4 it got me from silver 5 to silver 3-2 long story short i was on the climb
then tank meta season5 and mastery changes hit and yorick fell off (he needed that mana regen in the early utility) also lots of tanks means yorick can't secure kills as well as before.
now don't get me wrong i believe yorick is Underpowered and broken at the same time
the sole reason it worked is because with gold coin his mana issues were not such a big deal and once you got essence reaver you really started kicking people's balls( as an item it worked better cuz it banked on yorick's early game dominance muramana is a mid/late game item)
during this season i learned a lot about yorick and why he is currently in this state and why you can't just straight up buff him
that is simply due to the fact that he has poke and sustain in the same ability and this is kinda wrong. nami does it as well but her sustain is a lot lower, Yorick's sustain goes out of controll i mean half of his budget goes into this E of his and that's what i feel is keeping the rest of his kit down.
why not simply echange the sustain for the movement speed burst of his Q and vica versa? then he gets counterplay to his kit better chasing power on top of that and is no longer so overbearing once he gets one item or so. and then you could even lower his mana costs to a playable level
