Nostalrius Begins - Quality wow vanilla realm (1.12)

Hi all after quitting live wow few months back I'm feeling the itching of playing again but just found out about this server so have decided to give this ago as I never played vanilla. So my dilemma is which class to chose I've always played rogue as my main and had mage as an alt since I started playing at the end of TBC. Which would bring more to the plate in pvp? I may also play some pve so would like something that's going to be semi fun in dungeons ect.

Any input would be greatly appreciated
