Warrior or Unholy DK

I've played Outlaw Rogue when I first started BFA. It was pretty fun, though like people said it is also difficult. I find it difficult to maneuver in PVP situations. All though some of the best PVPrs prefer to play Rogue.
I recently purchased Shadow Lands and playing through with my BM Hunter at first, then might swap up with my Demon Hunter. I have almost every class besides priest and Shaman. I might play one of those sometime down the road some.
I've played Monk too, and have had a lot of fun.

Venge DH is incredible right now
