I normally have Nel, Albel and Sophia, but I try to train everyone, but I use this party of bosses and stuff. Nel and Albel do alot of damage and Sophia is a much better healer then Adray, Sophia really does level fast, Adray doesn't, I've tried using him, I just can't, he's level 15 and the rest are like 50-60, I just can't use him... but yeah, Nel, Albel and Sophia is my party team, I don't like using Fayt, and was very glad to find you didn't need to.
