Kindred ultimate is not visually clear
Maybe it's just me, i don't know, but i find really hard in teamfight to track the progress of the Kindred ultimate, it's a pretty big deal. The fact that is something you see only on the ground with no additonal visual effects on the champions contibute to that too.
What i mean is that when there are a bunch of people in narrow spaces you can't see how much time passed on the ulti (since it just glow on the ground) and sometimes you mess up thanks to that. Add in all the visual effects of the spells the players are throwing and you get the idea. I would love if you could see like a bar filling up over your head or something like that, that way you know that when the bar is filled the Kindred ultimate is finished and the heal kicks in.
Just a suggestion
