I haven't played the classic, but I know that some skills were removed. Feather drop, phoenix dive, tactical retreat etc. I have seen the NPC enemies doing it against you(in tactician mode, in the main quest- first beach battle before entering cyseal, one of the cultist performs phoenix dive and straight lands in between your party members. Similarly, in the escort job quest, one of the bandits does tactical retreat.). I think those arts looked pretty cool. I think I saw phoenix dive in one of the DOS 2 videos. I don't know why would they remove it and then add it again. Anyways, I am glad you added it back.
