What the first two guys said.
Some tips are:
Be druids, priests, or hunters- druids can shapeshift, hunters can claim there own pet thing to help them kill enemies, preists can heal, and they all can kill from a distance.
When picking talents or whatever you call them, they are like Fishing, Mining, cooking, skinning, blacksmithing, ect.
you can choose a few now since the game has changed. Whatever you do, get fishing! you can fish as long as you want and you can get a lot of money for it. I would also reccomend skinning. Because after you kill something you can skin it and make money off the pelts
thats preety much all the tips I can give beceause i don't play anymore.
