It's no longer possible to change details of an application once it has been submitted: "We will not accept any edit requests after your submission to the form below."
Does this apply to established PMFs?
Murdoc says Sovereign Justice Collective had theirs changed from Democracy to Dictatorship, which makes them immune to the negative effects of black markets. Hence, I agree with the OP that Dictatorships and other governments which shut down BM's are overpowered.
Should all player groups with Democracy, Cooperative etc governments follow SJC's example and switch to Dictatorships to even the playing field?
Or should Frontier consider Jmanis' and Walter2's suggestions that black markets should react more dynamically to State, rather than be set by govt type?
Personally, I favour the latter.
