I really love this mod, the ships are great and the derelicts that you can find make distress signals worth investigating, I managed to get my hands on a full fleet of Regalias and I love them (although they cost a fortune to keep operational) if I use multiple of those carriers with regalia gantries will it improve the supply usage of the Gundams ?
However there's also a few nitpicks I have with this mod;
First, the Great Houses ship. They're too expensive to buy considering they are always sold with 2 to 4 Dmods which means the cost of using a functional one is around 2 to 3 million credits depending on the size and that is not counting the appalling supply cost.
Second the ship system of the GH ships when used by the AI. The AI will keep using the burn drive systems constantly and will ram into enemies and allies alike (I nearly lost a rare destroyer by being crushed between a Legion and an Onslaught) I'm not sure why the AI seems to be so zealous when using this ship system specifically compared to regular burn drive but I think it's one of the biggest problems with the GH ships currently.
And finally the Legio. I think the size of their fleets requires tweaking, too many capitals and ships in general. They're impossible to tackle on until endgame and their Siege bases shouldn't be so strong from the very start in my opinion (unless you cannot make them upgrade their siege bases over time if left alone like pirates do) and they should have less fleets guarding the entrance of the system. Only way I found to defeat these bases (and that's when I have 3 decently sized colonies) is to go to Chicomoztoc and take a dump on the High Hegemon's head from orbit then use the bounty hunters that inevitably come to kill me to distract the Legio fleets away from the base (this tactic most likely doesn't work without Vayra sector or Nexerlin without the bounty mechanics).
