question about boss info

[Tempos]

Hi all, i just got back into wow after a break from wotlk. Been doing heroics, and recalled a small feature i rember hearing about during cata development, one where there are in game details about boss spells. I couldnt seem to find them, so been going to wowhead before bosses. Anyone know is this feature got scrapped, or if its only for raids, or if im just going crazy and this was something that never exsisted haha. Thanks

Unfortunately, this got postponed, but as far as I recall it's still on the table. They just haven't finished it yet.
