BC and wotlk servers

I’m still on the fence about transfers vs copies. I think copies kinda kill immersion and seem odd. It’s something that happens on the ptr of course but that’s different.
I get how transfers could negatively affect the vanilla realms. But I think without sharding they are going to have to utilize server merges and free transfers anyway even without BC servers in the mix. It’s the only way to keep the populations in healthy states.
