Hi,

it's kinda difficult to see the cooldown of skills - especially if you are playing on 2 clients, which together take only 1/2 of the screen.

My suggestion would be

1) to change the light-grey color of the cooldown to something thats more visible
2) or to add a 3 - 2 - 1 countdown in the remaining 3 seconds of the cooldown on the icon of the skill.

Thanks!
