New players wants to ask:)

Hello everyone!
I want to start playing here after 4years of wotlk and other expansions,never played vanilla before,so i want to ask you some questions.
How is pvp in vanilla? Is it fun and balanced?
Is there much to do in this server?
How are classes working? Mainly ferals,rogues,mages?
