In tight corridors they might block passageways with their dead bodies even after being defeated :P

On a more serious note though remember that Yomazu and his chicken friend were also just regular troopers. Those troopers are probably good enough to keep mages like Jet, Droy, Wakabe and Macao busy for a few minutes if they attack in enough numbers, while the top mages are kept busy by the Seven Kin of Purgatory and if that's not enough, through in some Tartaros mages allied with Grimoire Heart for this attack.
