So it's not that there [i]shouldn't[/i] have been a fight, it's that it happened far too soon?

And yes.

It's good to establish some relationships such as rivalries or nemesis, or just plain hatred, but not enact them so soon. If it is within the characters and setting to fight very soon then it is okay (eg. character A is overly aggressive and is often troubled, or school allows fights). Before you say anything, remember that Beacon preaches team work amongst Hunters, due to its purpose. Fighting one another for the sake of petty reasons, or internal conflicts in general, are heavily frowned upon.

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.
