As the title says, why exactly did Team SSSN transfer to Shade Academy when Haven Academy was just fine after the Battle of Haven? It was just a foiled terrorist attack like 2 or so weeks before Haven Academy started and yeah, the Headmaster Leo Lionheart got smoked. But it's not like the any actual property damage happened and there are always Deputy Headmasters/Headmistresses who could operate Haven Academy while they look for a permanent new Headmaster/mistress.
Yeah, I know meta wise, it was to introduce Vacuo via the EC Meyer RWBY books but the point still standing, Haven was perfectly fine after Volume 5 and wouldn't have been disrupted or closed because of the events in Volume 5. So why did Team SSSN suddenly transfer to Shade Academy instead, which is hundreds to thousands of miles away and would require quite a bit of work to move and get through paperwork, moving in, settling into the environment, etc.
