Hi

Im kinda interesstet in changing my Season Class. However I am unsure about a few things. In the [GM Notes] 2021 Summer Season is some information about this. 

If I change my lvl 57 Character to another Class, do I lose the progression of all completet Quests, so if i used the Simplified Main Questline, I have to start the whole Main Story from start again? Or do i just lose the XP?

The Warning: "* Warning! Quests that are in progress or completed on Class A will not be transferred to Class B!" suggest that I have to redo the whole main quest even if i used the Simplified Main Questline (and that i cant choose a second time because it its once per Family only).

I also did 56-57 with Chenga Questing, that I probably will lose.

Any experience Class changer here?

All my Questions have been answerd, thanks to EvilDoUsHarm:

Hello I have no experience in chaging season chars but the notes you mentionned seem to clearly imply that your completed quest will be lost upon transferring.

To be noted that this behavior is already present with regular characters: there is a quest counter in BDO that track your quests progress and if you delete a character your counter lowers by an amount equal to how many quests were completed on the deleted character.
