Just one problem, do you get a command point back if you rescind the command during the command frequency? Hopefully you still lose that command point if you rescind it, because it might get abused (although a lengthy process).
That's taken care of - if you rescind/cancel an order/assignment that opened the command channel, the command channel gets closed. If you give any "free" orders, stuff stops being refundable (to prevent "open channel, give free orders, close channel for refund" scenario). Let me double-check that actually works, though
Itl take a while to get used to
Honestly, I hope that it wouldn't - it's pretty much the same in the major points, and all the differences should make it easier to use by removing some restrictions.
