The idea is good, it needs to have prerequisites though, first of all, fix the host issues, second, this will be a LONG round from the description, not a regular 2 hour one, so only on Saturday is possible or Sunday whatever. After those are met, we need I would say at least 30 people or so for it to work at least somewhat good, if that is checked too, we need to discuss the time until NT begins their waves and their equipments, we don't want DS as you said. Someone would need to map it (I know of the cruiser, so polish it maybe?) and we need a goal for everyone. I like the idea of involving Syndicates, voxes and the derelict too, but maybe space ninjas? We don't use them anyways ever, so give it some use, I would say. and rebuilding the cruiser would be great, maybe give a goal to attack NT with it? We need to discuss a lot, but it would worth it, and I think I would have a lot of fun on any side.
In summary, do this!
