Good posting Lepton and Chutt. Now u2 get together and write up a rule. I'll check it out and put it up to a vote, but DH and I are liking where you guys are coming from.
If you are willing to entertain the idea of exempting line ships from disengagement rule, then I'd be willing to go with Chuut's language and idea. Any line ship is not subject to the disengagement rule no matter the circumstance. Period. Stop. End of sentence. All other ships subject to disengagement rule. For any potential last minute change like this, it would be best to keep it simple. However, I can see that this might seem to go too far, but if put up to a vote, then at least people will have a chance to register their feelings on it and discuss.
