As the seraphs are recent conquests of the government with Vegapunk's words contributing enormously to what I'm about to say now, the seraphs are the strongest fighters of the world government...
"Ah more sasaki kojiro the admirals were crowned as the strongest fighters of the world government", old information and that doesn't make sense to us anymore, while there was no change in C3 and in the military power of the government they could remain like that, but as there was the deployment of 2 admirals in the TS and with the government getting the seraphim, things changed.
The government is under the control of the strongest humans and unfortunately the admirals are human.
