I might have headaches for you.
My next holiday/vacation time is July 4-15. We have a rule here at work that at least once per year we should take 14 days of vacation.
My plan was to take these days for a time in Berlin - the family is still renting the flat of my father when he was working there. We use is for holidays like that.
Plans are to abandon that flat within this or the next year, so this might perhaps be my last chance for an extended sta there - which I'd like to take, since I love being there.
So, please, do compute additional plans for that, assumed that I might really do that. It would mean, then, that I'd be missing during 2 Fridays - the 8th & 15th.
Since I'm currently concentrating my main's role on both backup-healer/supporter (although I just cannot do much buffing right now) & slight damage, you wouldn't have that, then. (Do we actually have a main healer in the group ? I just don't remember anymore.)
The next 2 Fridays are not affected by that (24th & 1st).
Everyone should do the introduction quest. It's - in my opinion - required if you want to find out about the Isle Of Dread … If you don't know the adventure module, that is.
To me, it's new.
In my opinion, the intro quest is not meant to be a group quest, even although you can actually play it as a group qzest, too. There is just too much DM narrating there. Which you really should listen to.
