Mordekaiser passive idea: shield gen based on lvl
So basically my idea is to reduce the inherent snowballiness and lack of fallback pattern of Morde. Each autoattack and spell would generate a specific percent of the shield, different lor each instance of damage (like at lvl 1, 10% for normal autos, 18% for Q autos, 10% per unit capped at 3, etc) and have this percent scale with champion level, so that early on he has to rotate carefully his cooldowns and autoattack timers, and later on he can guarantee to kill and survive during a teamplayed pick.
He could also have a small, non scaling amount of absolute vamp with a minimum and a cap per damage instance (at least 8 and not more than 90 HP per instance for example) to keep a small incentive to build ad/ap instead of only AS/ CDR. It wouldn't be as snowbally since it would be capped AND wouldn't double-scale on offensive and defensive stats unlike current shield.
