It could be nice if in the option of the game we can add a little tool, on the right or left of the screen for see the timer of your passive skills
Like a little image and the name of the passive skill with next to it a timer in red like -3sec
and when the CD is ready the skill would be wxritted in green, so you know when your passive will proc etc…
for exemple for last refuge, if we can see the CD we should make less mistake!
