But Royi, What profession should I pick up????
I'm glad you asked mysterious stranger! Here are answers! My own pref is Inscription, Leatherworking, and Tailoring offer the most BOOM BOOM, but Enchanting and Engineering and Alchemy all have their bonuses as well. I'm full engineering on 3 of my 4 85's myself so I'm a bit partial to that skill as well.
