I have pretty much used the same type of addons since TBC when i started which is the usuall bartender, omen, dmgmeter etc.
But i felt like changing it up and i saw this video from a streamer and youtube personality that ive followed. I really liked his setup.
TellMeWhen and the dmg meter is Skada i believe? Dont know the name of the plates which is the most interesting.
Its late and i hope i will save time asking instead of searching
Cheers!
