Odd AI naval behavior

[crdvis16]

Has anyone else noticed the following AI behavior in their games?

1) The AI builds almost entirely melee naval ships. Like a ratio of 10-1 or more.

2) The AI is very hesitant to attack coastal cities with their navy even if they dominate the sea.

In almost every game I've played lately at some point I'll have a coastal city be "attacked". Its waters will be filled with AI melee ships who will then just idle around my city and let themselves get picked off 1 at a time by my ranged land units. They will have only a negligible number of ranged ships so they can't really fight back against my land troops and for some reason they won't attack my city. In most cases they could probably damage or even take my city if they would just commit to the attack but something in their logic is stopping them.

I assume this isn't a bug so not appropriate as a bug report and I assume it's not something that would make sense as a congress proposal? My uneducated guess is that the AI is doing a tactical calculation that determines that attacking the city is too risky but is missing that strategically it should probably be more aggressive with its navy when in a dominant position.

Well once again I invite everyone to test this, it should direct the AI towards more balanced armies/navies: https://forums.civfanatics.com/threads/unit-production-ai-tweaks-experimental.676462/ (doesn't influence how they attack with them tho, only what they build)

ive just about finished the above game and i took all but one of the ai's coastal cities and did not declare after i did that as soon as i finish it ill add more logs to it. AI War decs and sends units if its coastal its always melee ships and they get picked off. If is land theres a bit of variety but eventually they retreat, in the latest patches ive not lost cities. In previous patches ive had to have more units defending as ive lost cites.

Ah, looks like this is on the radar of the community. I'll try that experimental patch after my current game ends. Hopefully a tweak is in the works for their aggression as well.

I don't think it's a bug or unintended, since the behavior is quite human-like (only on the tactical side, not strategic part), but at the same time its build is still the same with old AI behavior (melee >>> ranged). Only need to rebalance their composition to have more ranged units and this issue should go away, with melee mainly tank/hold the line/not fighting losing battle unless it's enough to kill something, and ranged units take care of the no-counter dmg.
