I currently have a warrior (Prot/Fury) and a priest (Holy/Spirit) that I enjoy using. I want to add one more player to my rotation. I am having a hard time deciding and was hoping I could get some suggestions.
My requirements are that it has to have alchemy/herb as the profession and it would be a class that would be in high demand for raid pugs.
Since you already have a Tank (Prot), a Melee DPS (Fury), a Healer (Holy) and a Caster DPS (Spreist), the only thing you lack is a ranged physical damage dealer who has a pet (Hunter).
Going for Casters will be somewhat like Spreist and Melee DPS or even Tanks, you already have a Warrior for it. So, I'd suggest relying on a pet with a physical damage dealer. Although the class is easy, it definitely is extremely fun. You can go for BM and choose between Survival and MM for the second talent build.
