advent vs vasari?

Phase Missiles and the Subverters reduce shield mitigation ability negate one of Advent's stronger points The Mothership also seems kind of useless against them since Shield Regen is out, and with the above mentioned skills, doesn't last long enough to make use of Malice if focus fire. Other cap ships die just as quick, so it seems that the only way to keep them alive are to keep them out of battle until the mass of the opposing fleet (mainly Assailants) are gone, but I doubt that would work well Advent rely a lot on the cap ship skills from what I read on the forums. Are there any good strats for this match up?
