SaGa Scarlet Grace has some very potent status effects. A decent amount of bosses can potentially be susceptible to them as well. Taking off large chunks of HP through poison damage to landing a clutch paralysis. You won't just be using them against bosses, but regular enemies as well. There is also a lot more depth to Scarlet Grace beyond just useful status effects, like action distribution across your party due to sharing the same action point pool to perform skills for a turn, or setting up your counter attacks, interrupts, or disabling an enemies ability to do so.

Romancing SaGa 2 has decent usage of status effects so you can safely down enemies through blinding magics, or disabling enemies that can one or two shot characters with paralysis and stuns. Don't expect to cheese the big seven with status effects on the other hand, but you will be still using them for most of the game.
