Thanks guys, we are very glad that you are enjoying DW.
Regarding the fleet response, I think it's important to realize that's not an AI flaw, but a design choice. We looked at it in terms of whether the US would sortie the entire Pacific Fleet to deal with a piracy issue. The fleets are generally reserved more for full warfare, whereas the individual ships are meant for escort/pirate/minor threat duty. The fleet is intended to remain fueled up and ready in a strategic location in case of a more serious threat so that it's not out of fuel and out of position if war is declared. Based on feedback we will likely tweak that to make fleets more flexible, but that is the original design intention.
Maybe you could 'tag' each fleet with fleet mission like Support (this fleet stays behind other fleets), Main (this fleet stays refuelled whenever possible and engages hostiles in system or attacks if AI is given allowance to use them) and last but not least Intercept (this fleet is used to intercept attacking foes, pirates, whatnot comes to your area) and intercept has 'distance' options for Near (some max time it would take them to travel to the system?) or Distant (if there's enough fuel to get there without refuelling).
Or just allow you to make 'escort fleet' that acts like escort but is a fleet
