Though I realized Orlandu didn't have his Excalibur, it just struck me that he doesn't have his Bracer either at this stage. Although he's still got good damage, with the SSL penalty, like Dhyer says, that damage isn't as overwhelming as I initially suspected. The draining is handy, but when all is said and done, Orlandu is only marginally above average speed at this point, and if either Rikku or Nina dies, before the 4th fight, I don't think they can manage.
Going to change my vote on Grefter to a fail. 3-team parties lack the manpower to get far, I'm afraid.
