Most of the high-end hunts are indeed endurance matches. Zodiark, by contrast, has only a fraction of the HP but is a complete asshole, and the game forces you to get your gambits together to beat him as quickly as possible or you're going to have a lot of problems.
The Espers are a lot more buffed in this game. The more powerful ones can have HP in excess of 9999 (it just shows as 9999 unless their actual HP drops below that), and they can now do more than 9999 damage (so can your characters, for that matter, with the right weapon/armor combos). They can also now be controlled actively through the battle menu and even be made the controllable character while on-screen, whereas before they just followed their gambits, which includes choosing when to use their super attacks. You don't have to wait for the exact right one-in-a-million combination of circumstances for Ultima to use her big attack. With those things in place, the weakest link ends up being the summoner, who can still get dogpiled on by the enemies.
