Why is it "meta" for melee DPS to do the call-outs and countdowns?

What?

Never relied on a DPS to do callouts. Some talented people can, sure. But even as a tank main, I tell my group if I have to go DPS I'm not doing callouts. Unless it's something specific to DPS, like "I got this add" or in 11 savage where the melee calls out if they need a different color fist. On 06s we'd occasionally let a nin pull to start the countdown but that's kind of a weird situation because of the delay.

Never heard of this DPS calling out mechanics "meta"

But this is also in the PvP thread so I am thoroughly confused.
