Wouldn't it be thematically epic if Lee Sin provided no vision?
Got a cool idea where Lee Sin should be actually blind. But to compensate, we lower E cooldown by a bit and increase it's range by 70% as well as provide 1 second vision around Lee Sin equal to its range. Those hit with true vision provide 200 range normal vision around them lingering for 2 seconds.
These numbers aren't meant to be set in stone. They are approximate not-well-though-out figures as placeholder values.
Basically Lee Sin will always be debuffed with the "Blind" effect. Whereas blinded targets are given some vision around them, i.e. Rek'Sai or Quinn Q, Lee Sin gets zero.
What'd you guys think?
