Morde Shield Suggestion

Instead of having the shield be generated via % of damage dealt how about having each ability generate a percentage of his max shield strength based on targets hit?

Could look something like this:

Q: Generates 25% of max shield strength per unit struck. If the target is alone the shield gain is increased by 65% (41.25% max shield strength).

W: Generates 5% of max shield strength per second for each unit struck (max 4).

E: Generates 25% of max shield strength for each unit struck (max 4).

R: Generates 50/75/100% of max shield on cast and 10/15/20% of his shield for each second the target is cursed.

(All of this could be loaded onto the passive's description)

This way he doesn't have to build full AP to effectively recharge his shield. He won't be as useless to the team if he falls behind in lane since his shield doesn't rely on his damage output. This also removes some snowballing for the same reasons. Also, the 50% reduced generation on minions and monsters wouldn't be necessary here since the amount generated is fixed instead of scaling on the damage dealt.

Numbers all subject to change (they are blatantly overtuned on purpose).

Thoughts?
