I think I've finally landed on my main for Legion, warlock!
This is a pretty big departure for me, since I have always played healers, and I did nothing but heal until WoD. However, I took up ele shaman in WoD and consistently played it in the 95-99th percentile, I have several other friends that want to heal, and the guild I may raid with would only be able to use me as a part-time healer at most right now anyways.
Elemental lost some of the depth that I enjoyed in WoD(plus I don't like the artifact), but I'm sort of falling in love with affliction right now, and I like what I've seen of destro and demo, too. I'll likely make monk my main alt, as I dig both the non-brewmaster specs(I don't tank), and it'll be where I get my healing fix.
EDIT
I don't even really understand why they've removed gold generating missions? Like, people have been making absolute bank for years why suddenly become concerned a month before Legion?
I'm sure they don't want players to feel like garrisons and their tables are a requirement even after we leave Draenor. I'll miss the easy gold, but I'm already really liking not having to log onto every character, every day.
