Ezreal ideas for Essence Flux

I'm sure someone has already addressed this but honestly, It's such a worthless ability. I play Ezreal all the time and it would be nice if Essence Flux could get reworked into something different, nothing way too overpowering but something that rewards him for landing skill shots other than just some attack speed. Idea 1: Consume stacks on Rising Spell Force to cast Essence Flux to add a slow to the ability Say for 1 stack of Rising spell force Essence Flux gains a 5-10% (5% if attack speed slow)(10% if a movement speed slow) going up for each stack consumed when it is cast. Idea 2: A complete new ability also activated by Rising Spell Force's stacks once at 5 stacks of Rising Spell Force activate this ability to add an additional power to your next ability cast (similar to Heimerdinger's new ultimate) let's say Ezreal's Mystic Shot Splits into 3 weaker shots or Just gains a Powerful boost and then his Arcane Shift could shackle whoever the missile hits for 1 second and then for Trueshot barrage it could remove the damage reduction from when it moves through minions/monsters/champions. This ability would of course consume all Rising Spell Force Stacks and be on a Decently long cooldown. Idea 3: A change in Essence Flux Scaling to Attack Damage Idea 4: Another complete change in Essence Flux. Once at 5 stacks on Rising Spell Force Ezreal Fires off a Flux of Energy rooting the first target hit in place for 1 Second with diminishing affects on any enemies hit after (like a slow on others hit) if cast when not at 5 stacks it puts a small slow on the first enemy it encounters. The reason I started thinking of these ideas is cause of the lack of CC Ezreal offers with his rather low comparison in autoattack damage and his Lacking late game spell damage along with his short auto attack range the way I see it, he needs a auto range buff or a CC or just more raw damage to him in general. Compared to top tier Marksman like Jinx, Sivir, Lucian, and Draven, he doesn't hold nearly the potential when played very well. ultimately he needs more of a reward factor for Landing abilities and playing smart and well. Take jinx for instance, Amazing auto range (attack speed steroid on hit) AoE damage HUGE long range slow A decent shackle,and global execution ability so overall good CC Incredible Range with amazing auto attack damage. Thank you for your time and consideration.
