Hello Devs, I know you have a lot going on right now, so this is low priority, but I wanted to mention it while I was thinking about it. It would be nice to have an experience counter identifiable on each rune to indicate how much experience it has acquired. For example, how much experience does my Elven Taskmaster have? Oh yeah, it is "78" because it says it right there on the preview.
You can see the amount of CP on a champion in the rune checklist. It would be more useful in the manager if that is what your were trying to say.
I do not exactly know what you are saying. CP is what? EP is experience that the rune has acquired after some play. To my knowledge, there is no indicator for that.
