Why not temeo?

Ive noticed that a lot of older champions are getting reworks, why not Teemo? a simple thing such as changing teemos poison to a toggle able affect that requires manna to use, would make a dramatic change in his game play, or viability late game. By making the change to a toggle able ability, it should be able to trigger items such as and like or atleast make it where it gives you an ammo stack, "use: gives teemo 5/10/15/20 poison darts that do 10/15/20/25 (+.05*ap) for 10 seconds. 15 second cool down. passive: every 3 auto attacks reduce the cool down by 1 second." or have him build up stacks for his ammo rack over time, as it states in his lore, he collects his poison while in his periods of isolation. change his passive to give 5% max hp and manna per second while stealth instead of increased attack speed when he brakes stealth, move quick can be used while stealth for a short tumble and remain stealth (dodge skill shots) but it doubles the cool down of move quick. his title is "the swift scout" so he should feel fast, and scout like, meaning the ability to escape quickly and evade most enemies, while having the capability to fight everyone one on one with some type of extra burst damage.
