I was looking at the Vasari tech tree, and considering the worth of phase missiles. The description of the first-tier tech reads 'Phasing technology made small enough to fit into missiles, giving them a chance to bypass shields and directly impact hulls'.
My first thought was that, at low percentages, this could potentially be a bad thing. Normally, when you are fighting a ship, you first must work to break through the shields. While doing this, you are fighting the ship's natural shield regeneration. Once you have broken through the shields and start damaging the hull, you are then working against the shield regeneration and the hull regeneration.
With phase missiles, some of which will hit the hull, you are then working against hull regeneration and shield regeneration from the start. Phase missiles would only seem to be an advantage to me if enough get through to allow you to kill the ship while its shields are still intact. At the low percentage the tech starts at, this seems unlikely to me.
A question I did have was, 'Do phase missiles bypass shield mitigation'? If so, I could potentially see them as being more useful. According the manual though, shield mitigation applies both to shield damage and hull damage, so I would assume that they do not.
Has anybody found success with this tech path, or does anybody have more information?
