How is blocking people from deploying or doing combat missions after a 3rd star any different than a raid? If you want to solo the Rancor, but attempt to 3 hours after everyone else has, you can't. Big deal. Take your 0 damage rewards.
You don't need to post a 0 to get the rewards in TB so nothing is lost. Personally, I think it can work both ways to help officers and the rest of the guild. Too much time is demanded from everyone. Not having to spend time on missions that have been completed, and at the same time not being chastised for inactivity. Great! If you care about 114/114, communicate that to your guild and see if people will voluntarily back down. If not, either do a FFA and first come first served, or alternate between TB who gets to complete all missions.
My guild is 33*, and my biggest concern has been people using their squads in territories that are complete and not deploying to those that are not. 80+k tp for one squad might not seem like a lot, but if 20 people do it, that could hurt your chances for another star somewhere else.
