Having so many class specific buffs just make characters very overpowered. All class reduction skills and damage boosting skills on one character is like walking around as a GM without the stats. There is a good reason some skills cant be used by every class. I still disagree that these buffs should be given by that buffer. A solution to this is either keep the current buffs but restrict them to maps of the hideout or take away the class specific buffs so the npc becomes a way to get all party buffs easily.
