Show enemy trinket CD on default blizzard arena frames?

[Blurry]

I thought I remember seeing an option to toggle that on and off but I can't find it anymore :\

As far as I know, you'll need an addon to display the cooldown of an enemy's PvP trinket in arena. An example of such addon is Gladius.

Nope you only get that with Gladius or maybe Blizzard default frames from Blizzcon shows it. Nothing you'll find in game lol, that's cheating.
