Should have continued the war like it was supposed to happen in the so-called "master plan" that was laid out like 4 years ago, and have the reverse invasion of Gallia happen.
Also, Aland was completely pointless because everything that happened apart from the above was pre-planned around 2017 (or earlier, idk, I wasn't even playing Disco at the time). Though it seems like Enclave, fleet destroying weapon platforms, Confeds, Minarchy, Aland and possibly Omega-49 were all thrown in by Justin instead of the continuation of the war into Gallia (New London and Leeds were to happen 100%).
Had he not "quit", we would have had a lot more wonderful stuff that was as wonderful as the above.
A few off the top of my head that I got wind of;
1. A war between Bretonia and Liberty because;
1.1 Crayter wouldn't give Harris back (even though they wanted to).
1.2 Bretonia stole Gallic lane tech and started making their own lanes (rofl).
1.3 Bretonia for some unknown reason supported Hellfire Legion (nnnnnnnnggg).
2. An entire new cluster of systems called Lambda that stretched from Omega-49 connected "Wight" up to a Gallia connected "Algiers". Supposedly this was to distract Bretonia from destroying the Enclave. Enclave would expand into these systems too.
3. Battleship Athos would remain in Dublin permanently purely in order to "stop Bretonia from attacking Enclave in Edinburgh through Dublin".
4. Omega-49 was to be given trade lanes.
5. Liberty would connect to a system called Omicron Wau via a fully laned Alaska. I cannot remember why they wanted to do this but I think they just generally wanted to give Liberty a place to expand to to distract it, who knows how far it would have been taken.
The last action was to implement Imperial Rheinland, but I don't believe anything beyond this was planned. Kusari was mostly ignored, poor Kusari.
