Just got horribly annihilated as Vasari by an Advent comp spamming drone hosts. 
Now I don't want to get into any balance arguments here, but as the Vasari, what is an effective way to counter this type of spam? The sentinels didn't do much-new squadrons were built as soon as they were swatted down. Of course though, my army was quite small, since it consisted of quite a bit of lrf for the earlier disciple spamming the other comps were engaging in, and we know how fast lrf fall to strikecraft.
I had not yet teched to destructers, nor any of the support cruisers. I probably should have built a Kortal, but I had the Evacuator and the Destroyer and not enough credits. 
But enough rambling: What are good countermeasures for a joint disciple/drone host army for the Vasari?
