Disco diplomacy needs more critical approach, but that won't happen. Oh, come on, who can think critically here, it's just a game?
For example I'm not cool with Rheinland players, who think they just MUST hug Kusari/Gallia and shouldn't be fine with Bretonia. Or Bretonians, who're all about Liberty alliance.
Also Disco diplomacy needs more flexible approach, but I guess it'll never work well with vanilla lore. For example IMG-Gateway relationship. It's cool, but right now (and probably for last 4 years) it's hard to see they're close parthners.
