Fixing Pantheons toxic laning phase

I was thinking rito should add some power to pantheon late game, and also make him less toxic in lane.

Was thinking make his spear a skillshot, and make it like ryze, where you mark them with E and do more damage with the spear.

another really cool way to rework him would be making his damage centered around increased damage after an attack was blocked. like say if he blocks an attack he gets increased damage with his abilities. Would make his laning phase less aggro and more centered around baiting a fight so you could out damage the laner. What do you guys think?
