Why Sion's passive health is the worst passive stacking in the game.
%health / and %health true damage.
In every sense of the idea.. the sion passive health stacking is truly fail. You also need about 300 cs to make up the difference in most other champions. He has a low base health and low base health growth rate.
SO while you're getting all that farm to get what others are getting, EVEN when you exceed in cs and in getting those health stacks, you're just going to get smashed by the late game carries anyway who all have %health true damge.
You're also going to be getting cc'd alot more (late game CD on enemy champs will all be super low) so you will be performing your Q a lot less.

This isnt the winrate of a late-game super tank
and
say hello.
,

has a passive shield that even scales with his health, Mordekaiser's base health is very low. Despite the fact that
has a passive that lets her cast spells for free, her mana regeneration is very low.
and
both have a passive that gives them bonus attack speed, with Aatrox having an on-attack healing that activates every third attack, and Azir soldier's basic attacks scaling with attack speed. However, their base attack speed is low by themselves.
doesn't really suffer from this at all however and has a scaling up winrate for longer games (as he should).
