Suggestion for Improving Clarity on Kayn's meter from a PBE player.
Right now, the meter does not show you how much energy you have collected at all, unless you have fully completed the meter. I feel like Kayn player's should be able to see how much of a certain essence they harvested, so that they could plan their ganks in a way that allows them to get the form that they want faster.

The picture explains it all. The two sides are different colors and when they converge, the transformation screen appears. I believe that currently if one side wins, then it completely wipes out all of the progress on the other side, so that you have to farm more orbs of the opposite side or wait the 5 minutes if you want to transform to said side. I think that this design is fine, but they could also implement a system where how long the timer is, and how many orbs you need to farm, decreases depending on how powerful the minority side was in comparison to the majority side. If they were really close, maybe the timer would only be at 1 minute, where as if you only farmed ranged orbs, then you'd have to wait 7/10 minutes or some big number like that to get the Darkin form.
And yes, if you are wondering, I have posted a post like this on the PBE boards https://boards.pbe.leagueoflegends.com/en/c/champions-gameplay-feedback/Nezl4HaR-just-some-minor-complaintsquestionssuggestions-about-kayn-suggestion-on-improving-his-power-meter
