Question: How to build development? I mean, what's the meta here? I want more dev, so I can build more buildings, especially manufactories and shipyards so I can finance and have a giant fuck-off fleet of galleys to dominate the Med and make the Brits suck dick. But using mana for dev feels kinda wasteful unless I have so much mana I'm getting to max it out.
Building development when you can't safely expand due to coalition or other human player risk is for multiplayer. For single player comp stomping, you just do no CB wars across the map to open up a new front if you aren't good at finding co-belligerent chains that let you spread out everywhere. The ideal places to develop are level 3 ports in 5 province states and of course gold mines. (and isn't it weird how development doesn't matter one bit for great projects?)
Also, when you guys think is worth it to actually get a tech? I like those neat ahead of time effects for most techs. Is 5+ years difference good enuff?
It's probably best to get a tech as late as you can while still getting innovativeness, but there's really a vast mediocre stretch from between diplotech 9 (study technology) all the way to diplotech 23 (imperialism). All that diplo mana is best used for annexing vassals, keeping up the gold mines, diplomatic relations, etc. And then there's tag switching, if you're into that thing...
You can even get a beachhead in Britain by abusing "threaten war" even if you have no navy.
Some were, north Italy and some HRE land.
HRE is much less of an AE nightmare now thanks to the religious diplomats privilege.
True, it does help a lot, but it does seem like some nations that will get into the coalition either don't pop up or they end up entering later for reasons.
The biggest relations destroying surprise is getting excommunicated. It happens ironically when you pick religious ideas and start to take papal influence for granted due to conversions, and forget to keep the pope happy.
