Teemo's mini REWORK - Let me know what you think about it
This is just a small idea that came to my mind.
My goal is to make Teemo's kit more interactive, adding some utility to his Q and increasing the danger caused by his ambushes.
I would gladly receive your feedback!

P - Camouflage Unchanged
Q - Blinding Dart
Range: 580 550
Cost: 70/75/80/85/90 mana
Cooldown: 8 10 seconds
Active: Teemo shoots a dart at the target enemy, dealing them 80/125/170/215/260 80/110/140/170/200 (+80% AP) magic damage and BLINDING them for 1.5/1.75/2/2.25/2.5 seconds.
If the enemy target is marked with "BIOWARFARE", they are also affected by NEARSIGHT for 1.5 seconds.
W - Move Quick
Cost: 40 50 mana
Cooldown: 17 seconds
Passive: Teemo gains 10/14/18/22/26% 10/13/16/19/22% bonus movement speed if he hasn't taken damage from enemy champions, turrets or epic monsters for 5 seconds.
If an enemy champion marked with "BIOWARFARE" enters within 1500 range around Teemo, Teemo gets double the amount of bonus movement speed for 2 seconds when moving towards them.
Active: Teemo doubles his bonus movement speed for 3 2 seconds and prevents it from being disabled by damage.
E - Toxic shot Unchanged
R - Noxious Trap Unchanged, except for the fact that enemy champions damaged by Noxious Trap are marked with "BIOWARFARE".
Edit1: nerfed Q mana cost (back to live values); increased mana cost and cd on his W (back to live values); lowered W passive and active duration.
