I feel like it's pretty easy to get into it casually. I know someone will probably complain but there's discords for signing up and joining when you can and learning the raid.
As for wipe mechs ya do got me there. snow/fire ball prog be a thing. I don't consider the time to be an issue tho, especially with thinking it'll take that long to schedule thanks to the discords. It's current content afterall and people will be doing it for awhile! (looking at you 100 clears title)...though maybe my opinion might be a bit skewed on that thanks to living in pf hell in general.
Keep in mind I ain't against the normal mode, it was questionable they didn't have that...but I still do think it's not that difficult, least compared to drs or savages in general.
