For campaigns this kinda thing tends to be pretty awesome, but for the particular scenarios, unless you have a real reason to make it mandatory for every fleet (aka piracy is so high escorts are required constantly, or a large supply chain is on the way to the 'front' with a relief battlefleet or escort, etc.). Playing with both IN and eldar pirates, I am dying to get a small fleet of transports, tankers, and other auxiliaries for ambushes and raids.
