I propose to introduce into the game tracking the cooldown of the ultimate ability with a 200% charge as a separate icon.
At the moment, you can find out how much time is left to wait only through the interface window where all the skills of the character are located, and sometimes this is not very convenient, because everything is inconsistent there. Some prefer to allocate individual skills to a specific place on the screen so as not to waste time looking for the right skill on the screen.
