Tristana mini-rework?

I'm pretty sure i'm not the only one who noticed that her rework didn't work out that good and i feel she is the only AD carry whose kit just doesn't work very well and doesn't provide exactly the guerilla playstyle Riot hoped for.

First of all her passive on E needs to go and stay go.It affects lane management too much and most of the time it's a hindrance rather than a help.While it can help her pushing the lane also dealing damage indirectly to the enemy if they stand near the killed minion it creates a situation where you'll eventually push the lane back enough that a gank from the jungler becomes more dangerous if you still want to farm. Also her auto attack animation should be sped up with the cast time on E.

Some ideas that may help her push in a direction what would make her a good pick over other marksmen in certain situations giving her a well defined niche: There are just ideas,feel free to share yours helping Riot this way.

New passive on E: Hitting a champion with basic attacks x times(3) applies grievous wounds to them.

Active: Places an explosive charge on the target enemy.After 4 seconds the charge explodes,dealing physical damage to the target and applying a bleed effect that stacks based on how many times Tristana hit the target with the charge on.Detonating at full stacks turns the bleed into TRUE damage that may or not spread to enemies around the target.

True damage spread might be too much hence my wording.

New passive on E:Tristana deals bonus damage to champions that have been shielded in the last few seconds.

Active:Same as now however upon casting the charge will immediately destroy all shields on the target enemy.

This would make her an ideal counter agaisnt shield comps.

The following set of changes are more of an overhaul of her kit that pushes her into the guerilla playstyle and making her more of an AD caster than a generalist late game carry of some sort.So Tristana is now an AD caster with less of a focus on AS sterioids and more focus on raw upfront AD burst slapping an explosive charge on the enemy and send them hurtling to the enemy backline for an explosive finish to any fight:

New passive:Each level increases the AoE range on Tristana's abilities(E,W and R all scale with level up to double the radius)

Q: Tristana loads her next couple of shots with boomshots causing her basic attacks to deal mixed splash damage on impact.

W:Now has an AD ratio and deals physical damage.

E:No changes. In this case not sure what to do about the passive on E.It probably shouldn't remain here either because of her new Q helping with wave clear.

R:At the end of the travel distance,explodes in a large radius dealing bonus physical damage equal to %max HP of the initial target.Now deals physical damage.

In this case though her base attack range at the very least need to be changed to a constant value.Her spells' as well.

Any thoughts?
