On target CD indicator.

I know different champions have abilities that says, for X period you can not use a ability on them. Thus a on target cool down. But i know, from watching people playing yasuo on streams and on youtube. His E brings up a ball, or orb, along a Ring like track, that the orb follows to indicate how much time is left before you can E to them. Well i dont have that ring that pops up, just the floating orb/ball, no ring like track it follows, so i have to estimate how long it takes.
