No forced updates to current Classic realms, no opt-ins or opt-outs, no gold cap, no item cap, no "one char only" nonsense. Just plain 1:1 copies. Don't punish paying customers or they'll go straight to private servers.
The result is the smallest number of pissed off players.
Someone wants to play Vanilla? Fantastic. Don't even have to go anywhere. And here's a new, fresh start server if that's what you want.
Prefer TBC? No problem, your Classic characters are ready to go if you want to continue on them. Or here are these fresh start servers. Have fun.
Play both Classic and TBC? Oh honey, do we have good news for you.
Yea sure, you'll still end up with some pissed off players. That's life for you. But this is as drama-free as possible.
