Could we please get duration bars for high-impact abilities? (UI)
Based on the existing ammunition bar: https://i.imgur.com/1BJ7asD.png
Could we please get duration bars for abilities that are generally tied to periods of uptime/downtime, especially in the case of long-duration? These sorts of abilities are generally tied to "avoid the champion" gameplay and often have no clear indication for the remaining duration, by contrast to shorter duration abilities that often have audio cues (e.g. Kindred's ultimate) or area of effect abilities where the duration is often not what's important about the interaction (e.g. Morgana's ultimate, where getting out of range is the primarily gameplay). https://i.imgur.com/pFlAu0k.png
Ultimate recast windows:
Ultimate Uptimes:
(Riven and Swain could also denote whether recasts are available, such as being red if they are - Swain players themselves would probably also benefit.)
Non-ultimate Uptimes:
(I)
A case could be made for the increased-cost stacks on Kog'Maw and Kassadin, too; the dash-back duration on Zed's ultimate; as well as the buff durations on Lulu and Zilean's ultimates.
P.S. While I have your attention, could we add an ammunition bar to Akali.
should have a clearer duration like 
E that has a clear indication on its duration before it recasts itself (or in the manner of my favorite Champion Riven) those that can expire without having to make too much of a mess on the your Health bar.
