i think chung ha must be weaker at raids/missions than yega and lynn because she also good at pvp and afk. so she must be something universal for newbie that hasnt got many resources for character and he will choose chungha because she is good at all BUT NOT TOP AT ALL
I think quests must not be skipable, but it must be without needed recruits quest and ALSO CATOVIC QUESTS. Cath Torsche quests should remain because i get refined holy water there. So you should remove recruiting quests from kielce and armonia
