But that aside, my earlier question had not been addressed. Do teams have to participate in the same class for subjects that are compulsory such as Armory and Grimm Studies? Or am I free to just go where there are fewer people? I feel like canonically it's the former.

Nope!  Grimm Studies and Armory are non-compulsory, actually, and teams can split up for them if they so please.  For instance, all members of SASG are in Armory except for Abel, who is in Grimm Studies.
