We tried this mission a few times, last time yesterday with version 2.80.1.
There are a few things I want to say about this mission.
First, I have to say, that all of the Dominations out there, this is the best we tested. But there a a few things that make the mission unplayable for some of us. There are two features in Xenos Domination wich are essential for a Domination at least for me and the clan I'm playing with. That's revive and MHQ.
As for the revive-script, I don't know, what you mean by confusing. The last mission with revive (I don't know if they used the =BTC= script) was Dynamic_War_Sandbox_[VG]_v14n Public and there was neither a problem nor a confusing UI.
Maybe we just didn't find the MHQ. So, if there is one, where is it? If not, why?
