Several merc ships appear to be assigned wrong role (or at least a poor choice). Escorts are sacrificial units in a fleet as they are mostly targeted first and attacked until destroyed.  E.g. your expansive merc carrier getting blown away on its first battle is a real downer. It should have a support role (like normal carriers) vs. escort.

The Zindellit =survey ship:  escort; should be support

 The Praxis= Ideology points: escort; should be support, or guardian

The Retribution= fleet accuracy/jamming. Beam range;  Assault should be support, or guardian

Hivebase One= carrier;  Assault should be support, or guardian

The Bitte = Fleet +Move Cap; escort; should be support, or guardian

Safety In Numbers= Fleet +Move Cap, shield boot; escort; should be support, or guardian

The Gestalt = fleet accuracy/jamming; escort; should be support

The Scow =250 Credits each time it survives; escort; should be support, or guardian

he Linked Aerie=Carrier; Capital; should be support

The Helmder= Carrier; Capital; should be support or guardian

The Shaout= +fleet all defensives;  Capital; should be support or guardian

The Wraith= Fleet repair;  Capital; should be support or guardian

I may have missed some, and certainly some of my “should be” roles can be debated, but I think you need to take a look
