This thread was one of the reasons I started a beast/kin. I've been enjoying her immensely. I recently added Repel+Sudden Acceleration KB to KD (knockback to knockdown). Lots of mobs are resistant but plenty of them are not, so I get to stand in the middle of a gang of bouncing bad guys while my pets tear them up. I didn't expect this build to farm, and it can handle +1 purple elite bosses just fine. This build is also very welcome on teams because of SB and healing. Lots of fun!
