Toxic Shot - Now scales 0.3 (down from 0.4)
25% less scaling.
Wrong, Toxic Shot has two parts, the onhit damage and the poison thicks. the total scaling was down from 0.8 to 0.7, its a 12%-ish reduction on the total scaling.
Also, AP teemo endgame could do 400 magic damage on hit to 3 targets at same time with an at least 1.7 attack speed, and while that he aplied malady making himself and the ap carry hurt a lot more (about about 70 magic penetration + shred on Teemo with Liandry and magic pen runes+boots+mastery).
Season 3 Teemo had damage equivalent to an adc if you split his damage between the team (each shot doing almsot 1200 damage between 3 people in best case scenario), plus the oracles nerf makes his shroons much stronger.
