But i feel like 5000 could be a good number, they have to be careful about not allowing too many people online at once, as the vanilla/classic world scales poorly.
While today you can tag the same mobs, loot the same mobs, loot the same objects and have sharding to keep players spread. You have nothing of that sort in vanilla.
We can assume that a big part of their current subs will want to try out classic servers when they launch, especially if they launch in between patches. Aswell as a decent number of older players or unsubbed players wanting to get on and try it.
Excluding returning players we could make a guess and say that wow have 4-5 mil subs and atleast 10%(most likely more) of them will be online at the same time, giving us 400-500k players online.
then we can assume that atleast 50% will want to try out classic when it launches, giving us 200-250k.
with 5k pop a server that will be 40-50 servers.
Obviously a lot of them is gonna drop back out again once they realise it's not for them, so making that many servers will be a waste and having around 15-20 servers is more likely for the long run. With the option to add more if it ends up a lot more populare than thought.
But obviously this is by guessing and assuming a bunch of stuff, seeing as we have no numbers of subs or active players.
