I will make a suggestion and explain my reasoning down below, all this isn't even asking much, since all the OP champions have dummy CC combos AND sustain in lane. teemo doesn't have enough CC to survive in certain situations, nor sustain to keep up. I made these suggestions so that teemo's combo can stack w/each other, to better the use of Fervor/TL and various other items.
Passive: add some sort or magic dmg or dmg over time or make it able to stack AA/E dmg when coming out of Passive. make him able to move a couple steps before revealing, atleast enough to get behind someone near
Q: Make it a skill shot, but stronger by starting the blind once they proc off the first AA on you or an ally champion, and add poison dmg over time so i can sync w/his E. Make it possible to Blind more than one enemy champ some way, BUT if this was added, blinding multiple targets would be MUCH shorter than just blinding one champion (so everyone wont cry)
W: Add a jump, then Gain more speed over time while using your W (like running IRL, you gain speed as you run). Able to shoot mid air
E: Able to activate and deactivate, deactivated- just does a flat poison dmg so you can cs, activating it will do dmg overtime and able to stack X amount of times. Csing will give back an X amount of mana.
R: More slow % and slows mutliple times like rylais, but lessens the % during the slow time. i believe it slows x3 so it would look something like (50% 40% 30% // 60% 50% 40% // 70% 60% 50%) if not then i suggest a knock back into a slow, or a pop up into a slow. Able to one hit your own shroom making it have a bigger hitbox, but doing less damage and causing a knock back. Less mana on shrooms, since E will now have to spend mana.
-People dont even use teemo's passive as much as they should... some think its useless since they can see u go into passive and know what exact spot you are in, which is why i asked to be able to move A LITTLE bit, like the size of a bush or something. so i think they should keep the attack speed and add scaling ap, whether its over time (so sync w/his e) or just a magic damage (so it can sync w/q)
-Everyone always says teemo is the most simple champion, even though hes the squishiest. this will add more skill to his gameplay, but since he doesn't have many abilities to start, it would NEED to be buffed. because one missed q, i would die instantly.
-Teemo's w should have a better engage and disengage (jump, as far as a shroom can), the one hit to cancel it just makes it useless, against MOST champions. like garen... u can block his q w/teemo q, but he can just spin on u and cancel your w....
- Shrooms need more slow imo, most on hit teemos feel like they are "forced" to build mallet and think teemo is useless w/out it (which i disagree). but as an on hit teemo main, i feel like it is lacking CC. make it possible to bounce more than once, so you can either hit ppl from far away (like GP) or use them jump the long distances to rush into team fights
Teemo has the most flexible builds, but can even be more flexible if you make these changes, so you really dont need a big rework SeemsGood
This would ruin my hybrid ad/ap/tank build, that really is broken af, but i think teemo will be waaay more viable in games. and would see him in LCS if he was like this.
