Thanks for the suggestion! I've modified Cleave to give him a modest gap-closer.

I appreciate the thoughts! Let me see if I can explain my reasoning in response: 1. Enslave is supposed to be very strong, and potentially devastating. I had Mind Control and Cocoon in mind when I designed it. Like any heroic, it will be great against some compositions and less effective against others. Against many compositions, it won't be a great choice because none of your targets will be good counters to the rest of their team; all you'd get is a little extra damage and a few seconds...
