I recently revocated my MC, who was a minstril, and I found that in battle against strong enemies he has been close to useless. This is annoying because I have been trying to get Murdaws map from Baramos, and the battles have been dragging out. Anyway, the current strongest member of my team is a Level 77 sage, and she keeps the rest of my party alive. Once I get her to Level 99 I am reluctant to revocate her, since that will leave my party crippled. I have another sage, but he is only leveled up in the sage vocation, and I am worried he lacks the backbone to support a party. Any advice?
(P.S. The rest of my party is a level 68 gladiator, and a level 50 sage)
