The first time we see Garp fighting seriously, he displays advanced conquerors.
The first time we see the Gorosei fighting at all, they display advanced conquerors despite supposedly being carried by regeneration.
The first time we see Shanks use a named attack, he displays advanced conquerors.
On the other hand, we have seen multiple admirals (Aokiji, Greenbull, and Kizaru) fight seriously since the introduction of advanced conquerors and none of them have displayed this ability. I see no reason why Oda wouldn't show them using this ability if they truly had it so is it safe to say that they simply aren't conquerors?
