With the vision changes, Teemo could revolve around vision
EDIT-: some people told me about the problem with giving such utility on shrooms as soon as lvl1 which would allow to stalk precisely the enemy jungler. As a fix to that, I'm reverting the cooldown buffs and instead putting a charging time that scales down with levels until 11
EDIT2: Increasing ult throw range to be better than current bounce range. Increasing safety during ult for successful "missions", but reverting W buff. Reducing assassination potential with Toxic Shot's on-hit nerf (poison unchanged). Found out that actually the main problem with live shrooms is that 450 base damage rank 3, reverting ratio nerf, introducing base value nerf. Increasing max charges from 3 to 7 at rank 5.
OK so Teemo has been nerfed over the years because he's so goddamn frustrating to play against. The main source of frustration is having to back after ONE shroom lategame, being handicapped in your roams all game, being blinded while you farm all laning phase long... This season there's much less vision around, so vision scout would actually be a decent niche for Teemo. Here are my suggestions.
Q: changed to vision reduction like Quinn. Applies poison.
W: unchanged
E:
Passive: still Toxic Shot. Poison unchanged, on-hit ratio nerfed from 30% to 20%.
Active: Noxious Trap. 30/40/50 mana. melee (175) casting range, can't hit idle monsters (so that scuttie doesn't remove them),. charge time reduced by 6% per level from lvl 2, and caps to 60% reduction at lvl 10, reaching 13.6 base cooldown at lvl 10.
Max charges 3->3/4/5/6/7.
Base damage 200/325/450 -> 60/80/100/120/140
R: Passive: Teemo and his wards and shrooms gain 10/20/30% vision radius. Active: Teemo drinks a potion that renders him stealthed for 15 seconds and grants him 20/40/60 ms and ward detection, consumed after 2 wards. During this duration, shroom gains 1200 range (as a reference, Xerath's fully charged Q is 1400) and explodes on landing if it lands on a unit. All shrooms deal 2/2.75/3.5 times the damage during this duration and give a Nocturne's ult vision reduction effect for 2 seconds. Autoattacking (except wards) and using Q breaks stealth for 4 seconds, using W doesn't break stealth, E breaks stealth for 0.5 seconds. Cooldown: 110/90/70
Tell me what you think about it.
