Mounts done right. "Flying" mount done amazingly right. Masteries felt more boring and similar to each other, but the mounts themselves were great.
Story: Loved it. The tone could be a bit darker/more serious but the Canach/Rytlock dialogue was hilarious in a good way.
Elite Specs: Cool themes, mechanically decent, could use some tuning numbers-wise. Deadeye rifle feels really lackluster, waiting for malice is boring when you could just go daredevil and do the same damage without waiting.
Zones: Completely 100% perfect. No waiting around for zerg-type setpieces and repeating them ad nauseum, actual exploration that feels rewarding.
