Update:
After conquering Cleves and Utrecht with separate peace I got screwed because I had my king sieging and so he was the general at like 2/1 instead of my general with 1/6 shock fire. I would have beat the army I set a trap for before the other army arrived and probably ended up winning. Instead with mere days to go they loaded in and totally stomped me. So while I didn't get Friesland I still got the lands I needed to go after Burgundy who has been crippled by wars. Sadly now I'VE been crippled by wars. I totally forgot about the king thing. What I should have done was let that guy die and tried to intercept the smaller army. If I had ended up winning this crucial battle Austria would have been ruined militarily thus allowing me to finish attacking them and claiming Friesland plus a sizable amount of ducats, which I could have spent paying off loans while my still incredibly large army healed up a few thousand troops and prepared to stomp Burgundy in 6 months to claim Antwerpen Zeeland and Freda which also would have given me a line of provinced to Cleves so I could start coring it.
Fuck you Paradox for making the little known rule that shitty monarchs must lead all battles they are a part of even if I was only using him as a leader for his 2 points of siege which I had to Google to find out after wondering why my 1/6 general didn't crush my enemies into dust for me. Why the hell would you just not average or take best stat of all generals on each side of a battle anyways as that is what historically would have happened? In a non Ironman game this is probably where I would either use the manpower cheat or savescum to pretend that battle never happened. Its going to set me back about 20 years once I tally up all the various consequences like losing 5 years of manpower, losing 80 ducats instead of gaining 70 and probably missing me chance to gank Denmark while France was still sieging them and stomping all their armies to claim Picardie.
Sad times ahead for the poor Danes.
In my current game I got curia control from the rng at start. This helped IMMENSELY. I still lost 3 Teut lands to Poland but I managed to get other stuff instead.
I just finished enforcing a PU on Hungary. Even with 3 Italian allies and crappy armies on their side I still burnt through 100% of my manpower and had to stop paying off loans for a while. Somehow I ended up not fighting a single battle with my fleet, which blows since most of my power is in my massive fleet. Well actually the Italians beat but didn't damage my 10 Barque Lubeck trade fleet.
Most of my losses were due to siege attrition which is massive since I had to take down all but 2 of their lands even with winning every single fight and having the war goal bonus. I had the hardest time getting there too. I had to get mil access from Burgundy, Bavaria, Austria and 2 HRE minors. My first route close when the Palatinate revoked mil access which put 1 of my 3 12 man armies into exile status so I had to march all the way back across Europe to my fleet. Sending 3 12 man armies across the entire continent was nervewracking. Getting exiled, taking so long that Hungary got an heir and shit. During the multi year sieging period where I had 3 mil leaders with 1 1 and 2 in siege while having to siege 20 lands with no cannons I was immensely afraid they would get an heir. Once they won I had to counter the 113 negative opinion of me before my stupid king died. Terrifying. What if I lost my PU and wasted all that time, money, and manpower plus the 30 AE? Currently I managed to get to 100 opinion and my king is alive with a semi decent heir. I'll got from 2/4/2 to 1/4/2. Big bonus of forcing a PU on an awesome country like Hungary? No stupid coring costs and no overextension.
In my previous games my first two heirs were 6/5/3 and 5/3/3. Needless to say I am super poor in admin points at 2/4/2. Hell even if it didn't take 10 freaking years to core crappy Nov provinces I still couldn't conquer land anyways since I have no ADM to spare. Also I'm multiple techs behind in every category, well only 1 behind in military, due to stability and coring costs. Its 1490 right now and I have only one idea set, Diplomacy, and only filled 4 levels. Once I get to 7 in 10 years or so I'll have to take Naval Ideas so I can head for England. Luckily having level 3 or 4 DIP tech is not that harmful until like 1550. I really hate the behind in tech monarch point cost nerfs though. I should be saving like 500 points because of how farm behind I am in dip tech but no...
Now literally the only thing I can do is pray that in 50 years + integration time my PU with Hungary will pay off. I'll have tons of money, tons of troops, be able to pincer Poland/Lithuania who are PUed and finally get those 3 Teuton lands plus maybe some bonus lands that Lith has in the Baltic node, and finally have a whole other area to fight wars in where the AE won't cross over to Europe. Denmark has the worst time ever trying to expand because Muscovy and Poland/Lithuania wall off the East and the HRE is not a safe expansion area due to massive AE and those extra opinion nerfs to the entire HRE. I already had to give back Lauenburg because Austria gave me the return it or suffer huge penalties warning.
And anything below Friesland is too far away to fabricate claims on and I can't afford to take 2 point stab hits. Until my manpower and armies recover I cannot even attack Burgundy because taking Friesland to get into their sea node to forge claims is impossible with Bohemia and Austria and the rest of the HRE trying to defend it.
I had Lithuania to help me until taking all of the Livonian Order and 60% of the Teutonic Order pissed them and Poland off and then they got PUed and so Poland told me to fuck off. Now my allies are Hungary, which will finally help me again now that its PUed, since my recent fights were too far away for it to care, and Bavaria which is my dynasty. I have the chance to force a PU on the Palatinate but its not worth it with their allies. Currently if they die its me vs Scotland, why would Scotland have a chance...
Hopefully I can win the succession war and cripple them for an invasion 5 years down the road. I think that since I didn't join the HRE till I was too large because Austria used to be mad at me my best shot is to break up the HRE entirely. Then finally Denmark will take its rightful place as the ruler of Europe, with a focus on taking all the coastal provinces. Eventually I'd like to take not only all of Europe, Britain, and the Med coastal province wise but maybe Africa, too. Then maybe pop the coastal lands of all the Americas for that delicious trade money. I doubt I can get a WC but I might be able to conquer literally every single coastal or island province on the whole map.
