As you can see I've created a checkpoint of sorts to this point where I have all the required provinces except for those of Ming and one held by allied Aytthuya (had a pretty good run so far including a 14-year 4/5/6 queen regency for the current 5/2/5 king and I'd rather not go through the trouble again). Now I'm looking at my options for handling Ming, and judging by the displayed warscore costs (these are accurate, right?) I'll need a 61% score war (-war enthusiasm) to get what is required (douchebags almost fully annexed Mong Yang, taking 2 more Burman provinces and denying me that gold mine). The most important questions here:
1. Keep consolidating or start preparing? Current FL is 27 which can be brought a bit over 30 with some state/autonomy management, and that's probably enough to win battles with soon to be unlocked defensive ideas and tech advantage, but it's only enough for 1 stack and with the long travel times especially to Tibet Ming is going to get some easy warscore occupying whatever land I can't defend. On the other hand I still need that province from Aytthuya after the war so time is of the essence.
2. Declare war or get declared on? Naturally, getting allies (in addition to Ay and Lan Xang some potential allies include Chagatai and Gujarat, and Hsenwi is a vassal... not that they contribute much except a mountain capital for a defensive advantage) would be a boon, but I absolutely hate strategies that involve getting DOWed because it's bloody unreliable (for reference, I already did a test run where Ming never declared in 10 years despite me being in some stupid and exhaustive wars against the Indian sultanates and going neck deep in loans) and those allies would also lower warscore from battles, which I can't really afford. If I were to declare war, I could probably either easily defend the wargoal or I could just go nuts and declare for the Mandate for that sweet 50% warscore reduction. Ming often mothballs forts after exhausting themselves on wars with the hordes (IIRC, neither Chagatai or Oirat is a tributary yet) and it wouldn't be impossible too beeline for Beijing if I bring a few cannons with me, but naturally the problem is I would need to build some forts and hope (and save-scum, I guess) they hold until I get back for relief.
