Zilean E change proposal

Hello there League community and Riot,

I'm here to tell you that the current Zilean E is much weaker than the previous one due to movespeed slow/haste caps, 99% is weak due to that.

Proposed change: you already have a formula for "distance -> value" even on dashes! used on Yasuo. ( eventually removed from dashes however )

I'll keep it short,

To aid Zilean in landing bombs and staying relevant while giving opportunity for reaction aka "counterplay";

ACTIVE: Zilean bends time around a champion, Slow icon slowing an enemy or hastening an ally by an amount for 2.5 => 2 -> 4.5 seconds

NEW: depending on distance travelled, Zilean's time warp effectiveness will be increased to a maximum of 70%. The distance Slow builds up with gapclosers as well to help fight mobility creep.
