TEEMO IS BEING REWORKED?



So I just went to que with my friend, and hes Teemo main. but he couldn't select the champion and neither did me? it had a text when you placed you're mouse over it and it said "Temporarily disabled" (heres a picture: https://gyazo.com/1de72b2a5e1781405568b14ab3d4650e)

So is it getting reworked? oooooorrrrr.......?

My friend said that there were a glitch that you can have crazy attack speed with Teemo's passive (heres a video: )
So are they fixing that or is there a rework coming?
