Nostalrius Begins - Quality wow vanilla realm (1.12)

Wanting to make a healer and would like some information about Shaman and Priest. What are the styles for endgame both pve and pvp. What are in more of a need for the server, and really anything else i can learn about these two. Thanks ahead of time

You will be able to find a guild whether you are a priest or a shaman, just play your class correctly and you'll be fine.
