Idea for Pantheon.(Ability mechanics ONLY, stats won't be shown, or used. Just abilities.)

This idea is something I thought of while playing Pantheon. All feedback is accepted and Appreciated.

Passive: Privileged to Die: All damage that Pantheon deals will critically strike enemies below 15% HP. To Balance this, I suppose, would be to lower the actual Base crit damage that Pantheon deals.

Q: Spear shot: Upon activation, Pantheons next basic attack will throw his spear at the target enemy, dealing increased damage, and applying on hit effects. The Spear shot counts as melee. I didn't like the idea of a Skillshot Pantheon Q, and it being a select target ability didn't appeal to me either, plus, the 'Activation' part of it works well with the idea I have with his W.

**W: Aegis of Zeonia: PASSIVE: Basic attacks and abilities gives pantheon stacks of "Aegis Protection". At four stacks, Pantheon will block the next Basic attack from non-minion enemies. WIll also block a single turret shot. ACTIVATED: If Pantheon has full stacks of "Aegis Protection", he will dash a direction, dealing Physical damage on impact with Non-minion enemies, stunning the enemy hit for 1 second. The impact damage of AoZ is reduced by a small amount per minion that it passes through. If an enemy champion is struck, that enemy will be unable to break aegis Protection, but will deal reduced damage to pantheon. All enemies near that enemy struck, will be able to break Aegis Protection, but will also deal reduced damage to Pantheon after it is broken. ** *The activation of Q does give a stack of Aegis protection, as well as the basic attack from the ability, BUT, if an enemy gets rid of the Aegis of protection, the activation part of this ability isn't available until he gets full stacks again. *

E: Heartseeker Strike: Unchanged, for the most part. No longer has the passive to it, as now it is his main passive.

**R: Grand skyfall: After a few seconds, pantheon leaps into the air, landing wherever he marked. All enemy champions inside the Drop radius take Physical damage, this damage is decreased the farther they are from the center. ** Only change here is the damage type, and possibly the time it takes to drop.

I'm sure this will get a lot of negative feedback, but oh well. I wanted to share my idea, so I did. Please post what you think.
