Replying to the quality shitpost posted earlier today, the bandaid idea is good and all, but if you think about it, you can ping your ultimate status ("My ultimate is not ready/My ultimate is almost ready/My ultimate is ready"), so when Sage taps her Heal key when its on cd Sage should say something similar ("My heal is almost ready" or something). Yes, you can press Alt and see if Sage's heal is on cd or not, but that neat trick doesnt help you if you are the one playing Sage and your 4 bronze teammates doesnt know about it.

Thanks for coming to my Sage Talk
