Change the Root on Lee Sin's R into a new CC type that allows usage of Flash **OR** remove R-Flash.

The purpose of the root on Lee Sin's R is because it's still a point-and-click ability, just one with a lengthy animation. Therefore, it'd look weird if you had walked away, but then once the kick finally hit, you'd basically get yanked back to the trajectory you would've gone if you hadn't moved, instead of based on your current position, because the kick was based off your original position and it wouldn't matter where you walked. Visual clarity issues and all, not to mention just being stupid confusing.

Thus, I propose changing the 0.25s Root to a new CC type that would allow Flash to change the trajectory of the kick, similar to how Lee Sin can do the same (R-Flash before kick hits).

[name of CC type here] Affected unit(s)/champion(s) are immobilized for the duration and cannot use any movement abilities except for Flash and Teleport.

This would prevent stuff like some other regular ability or item from bypassing it, similar to how it is now, but allow for Flash to counter it. (Teleport was just put in there as it is the same clause for Root and is considered a movement ability as well.) Creating this new CC type would also allow for other future champions to have similar mechanics as well.

Alternatively, you could just remove the R-Flash interaction, but I think the former option would allow for more interesting and complex plays from both sides, instead of just from Lee's side as it is now.
