What's the addon with cooldown on potriat icon?

[SlappyWhite]

like for dots it makes the icons under the enemy potrait have a countdown instead of just the picture

[Ashrana]

ALmoste every dot timer does that. Like forte and dotimer.

xperl also does this as well as lots of other things; it's not a light-weight addon though.

[granbr]

yeah, xperl, pitbull.... a lot of them

[grimkiller]

I use XPerl, then in the settings there's something like MY BUFFS that you can make the icons larger and have a countdown on them in the form of a sweeping dark fade. I think you can have it display countdown in numbers too. I don't recall honestly. The dark fade is good enough for me anyway.

I use class timer, very good addon that works for me

You're probably looking for: OmniCC

[Horrid Crow]

OmniCC is the best one for that. It's light, no need to setup and does only the job you want in this case.
