What do you want to see in LoL?

Knowing when an ultimate is up =/= Countdown timer.
It could be down for 5 more seconds or 1 minute, you can't see that and you'd have to ask to find out.

Or you could have awareness of the dots, and a general isea about how long CD on ults are for the champions that you're playing with, but I get what you're saying.

I think best solution for this would have the dots have a clock like CD shown like every other skill.
