First of all I am impressed by amount and rapid deployment of hotfixes. Shows real commitment when a hotfix drops on weekends. Now some feed back on campaign:
Citadel
works as intended i can keep my BBs around 19% pitch. One thing bugs me tho - citadel on DDs is there one? Designer shows that there is but should it?
Diplomacy
While tension system works and you can prolong (or shorten) peace time before first war for the life of me I can't get AI to peace out. None of victory conditions seem to be working - I've never seen a war summary screen in 1.06. Revolutions come and go, blockades are lasting for years AI sends peace offers I accept and nothing happens.
AI designed ships
The biggest problem I have with AI designer is underpowered ships (compared to players). In current and previous campaigns I tend to design capital ships to be as good as possible which is reflected in their price - current BB is 200M. AI spams BBs worth 40M. 30k displacement, 17knt with 10 11.1 inch guns and really bad armour vs 44k displacement, 31knt 9 15 inch guns decent armour (i can't say if its good or bad never lost one). I think that AI should build ships after player designed their and try to match player's creation or at least try to get their ships in similar displacement and price brackets (like +/-10% on both stats). Reasoning is quite simple - ships were not designed in vacuum. Nations always tired to counter each other. That also solves problems with beginners - they would meet ships that are comparable to theirs.
Tech tree
Research speed is well adjusted my only concern would be researching techs that are barley used by player - I've never ever used 9 or 10 inch guns but i am forced to get them to mark 4 before i get first 16 or 15 inch. Somewhat same with range finders.
Bugs and tid bits:
VP bug, damaged ships turning on dime (essentiality spinning in same spot), travel times - it took 15 days to do transatlantic cruise in 1830 but it takes 3 months to get from Mediterranean to North Sea. at 18 knots 4000 km journey should take like 5 days.
Other than that perhaps I would put the gun adjustment system in tech tree (replace couple techs) to give fighting chance to DDs and TDs. Perhaps gun layout tech for side guns could be fused with centreline and in that place you could insert +/-5% and +/-0.25 inch tech?
Keep up the good work! I really like how the game is evolving!
Edit: Just got first peace deal. it turns out all 3 alliance members have to agree for peace before they start a war again.
