Decent guide, I find that most romulans are lost in the 4th phase.
It is so crucial to stick to your zone, most people don't even know what zone is what. Of course those people won't come here to read a guide.
Phase 1 is fairly simple with 5 people doing their job.
Phase 2 can be done, there are a lot of hidden containers behind buildings. The phase isn't crucial.
Phase 3 I kind of disagree on the strategy. Roaming salt vampires are kinda low priority, take out the source fast, then make sure no buildings are being destroyed, then take out the walking ones. A half decent team isn't going to lose a building, they should take barely any damage.
Phase 4 is a potential disaster. One confused person that pulsewaves will take out most of your romulans. One person scouting ahead is also a good idea, they can pull and agro vampires before they have a chance to get close.
Phase 5 is pretty easy, a few people can form a perimeter and the other couple float to problem areas, you shouldn't lose any really.
I like my theory that it reinforces certain buildings better than others. When private queues come back, you should do some tests and figure out what it means.
I'd like to believe that too, but I haven't seen it happen to me yet. Ironically, even with the private queues back up, I can't get 19 other people together simply for the object of testing this one, so it's just trial and error with complete strangers.
I personally think the biggest problem with players is that they run across zones shooting at whatever Salt Vampire they see, often leaving their home team woefully understaffed.
Did a PUG once where a female toon ran off after a hatchling. By the time she came back to do the escort stage, we were down to five civilians because we didn't have enough people to defend some of the buildings. Obviously, he/she was rather flustered when this was pointed out to him/her.
