"Ancient Storm" Champion Idea

So I've been tossing this idea around my mind for a while, and I was thinking of an ad caster/bruiser.

Passive: Ancient One Is really old. Does absolutely nothing but make the champion glow when eye of the storm is not on cooldown. Q: Light Rain Targeted ability that marks an enemy and deals a minimal amount of damage and makes them vulnerable to ad attacks by the champion for a set amount of time (aprox 3 sec.) W: Howling Gale Aoe Cone that pushes enemies away and strips them of buffs for .5 seconds. if it hits nothing but a wall, it pushes the champion in the opposite direction the move was cast. E: Storm's Edge AD, Def, and MR increase for .5, .6, .75, .90, 1 second. R: Eye of the Storm Passive Effect: at first rank, increases Ad. at second rank, double's atk speed. at third rank, triples attack speed (not stacking with second rank). While on cooldown, the passive abilities drop. Active Effect: Marks 5 points only the champion can see, becomes untargetable, and jumps between them, inflicting massive damage to those along the lines created.
