Recently new Federation ships were added to the NPC groups. These all have special abilities that are similar to those of the players. The problem is with two ships: Galaxy w/Saucer Sep, and Multivector Assault.
They will use those abilities regardless of the fact they have been reskinned as another vessel. For example, I received a review that a friendly Cardassian Galor separated into a MVAM Escort during combat. That really ruins the immersion.
We really need these new ship types removed from the Foundry. Anything that separates into different vessels should be disabled for Foundry mobs.
