I could probably find the answers with a bit of googling but forgive my lazyness :). Not rly that good at searching either tho so might as well ask here.

1) whats the plan for when official Legacy servers come on, gonna just resume per normal i assume but just wanna check.
2) how old are servers (Wotlk)
3) whats the timeline
4) which server would u suggest to a new player
5) is it possible to switch characters from server to server

Ty :)
