Turret Martyrdom--let's Advent turrets fire a single very long range and high damage beam at single target and then self-destruct.
I wouldn't make it destroy the turret, just have a really long reload time / use a LOT of anti-matter. This could be a 'loyalist'/'rebel' ability? Loyalist or Rebel would have stat effects.
Adjudicator Focus--let's the Solanus Adjudicator focus fire for increased damage versus a single target for a short amount of time.
Yes, an ability 'ish' that would be similar to what is on the Kanraks for Vasari. (Again, a Loyalist/Rebel ability?) Loyalist or Rebel would have stat effects.
Long Turret Ranging--let's turrets fire a weaker beam at longer ranges for a short period of time.
This again should be an ability upgrade that is available. Perhaps the other choice for an ability could be 'short turret ranging'.
Fighter Martyrdom--let's Advent strikecraft suicide strike and do damage as phase type weapons for a single suicidal attack (imagine the cool graphics here).
While this is cool ... I think it needs to be tweaked. Rather than suicide as an actual ability (since they are re-working strikecraft anyways) why not make it a 'if below x health' it detonates it's systems / soul / whatever-juice next to an enemy craft. The resulting phasic radiation bypasses shields?
