User blog comment:Lilxtiger/Teemo - Rework/@comment-24036535-20150812023005/@comment-5588011-20150812124253

The idea is that Teemo remains short ranged. In this rework he gains even more mobility, effectively having 3 Vayne rolls on a short cooldown. The ultimate change shifts some of the DoT power into the On-hit. Flash for one measley 30ish second CD ultimate that has numerous charges.

Also the W actually makes Teemo more stronger mid-lategame where he can afford to roam more and effectively give immense vision control. The idea is that while he may lack in damage late-game a strongly placed blind on an ADC with its increased range, can win games, the increased duration on his passive means he can apply it to more enemies more easily.

It's fine is Teemo remains this annoying little champion. It's not okay if Teemo remains this annoying little champion that has no counterplay.
