To elaborate a bit:

Mass Recall: Teleport ships from any location to the caster. For now, it'll be enough if you come up with a way of teleporting 1 ship. Best would be if it worked over multiple gravwells, but if you can't change gravwell allocation without phase jumping, tough. My problem here is that the only teleport buff actions I know are TowardsTarget (Distortion Field) and TowardsMoveTarget (Microphasing Aura), neither of which will point towards the ability caster. There also doesn't seem to be a MakeTarget or MakeMoveTo action which would make either of these work.

Combined Shield: Like Shield Projection, except all ships in the AoE should share the damage equally. The ability is supposed to be used by a capship, and should apply to all ships in range, not be cast by each affected frigate individually. So if you have 5 ships affected, and one takes 100 damage, each of them takes 20dmg instead. I tried it with a CasterAoE->TargetAoE->TargetBuff setup, where the AoE buffs spread the next buff to anything in range, and the TargetBuff gives 100% damage sharing. This ended in the original caster taking all the damage. (Also happens with 50% dmg sharing, attack target takes 50% and original caster takes 50%)
