The problem with most champion concepts that people come up with...
...is that people come up with a unique idea for WHO the champ should be, but don't come up with unique WHAT ideas (what they do such as abilities/gameplay). Sure, a cyborg unicorn would be cool, but if its only abilities were a damaging skillshot, a stun, a stat boost, and a damaging ult, that provides extremely unoriginal gameplay which would mean that there's no reason to play the champ, and if no one plays the champ then its just a waste of time. So please, if you come up with a unique idea for a person, make sure its abilities are just as unique.
Essence Reaver use the same mechanic but instead they just made it a less powerful copy of
Bloodthirster for Mana.

Your position is untenable.

's for all
cough
's ult works on champions who don't build ability power.
