Teemo's shrooms and Blind.

The shrooms of doom: Teemo
Alright to start this off i just wanna talk about Teemo's shroom count. Teemo seems to be able to place an unlimited amount of shrooms across Summoner's rift, and they all have 10 minute duration, and he gets a new shroom every 25 second (not to mention cooldown reducing items)....so he's blanketing summoners rift in shrooms.
What should be done:
Teemo's shroom duration i don't mind, but the fact that they remain even after he leaves an area...well it's infuriating. So as it stands...he can almost mindlessly place shrooms and know that it's going to get some poor champion trying to flee battle and base later in the game. (Or just a max number of shrooms should suffice.)
** Teemos blinding of &%$@%$$**:
I'm make this paragraph straight to the point. Nerf teemos: Q. Why? Because the blind duration is enough to make any adc (such as myself), not stand a chance early or late game...
[Sorry, this is not very into detail, as i would imagine others would have their opinions to share along side of mine.]
