Actually DLC worth the money
The really sad thing is that the AI was much better some versions ago.
I haven't played a minute in 1.30.
The AI in 1.29 is already very weak. Problems with economy, passivity of forces and so on.
For some test reasons I have gone back to 1.22. AI is way more aggressive and reacts to my movements way quicker.
For several versions features were added, that might (or might not) offer some flavour, historic accuracy or realism. But from a point of strategy these features give little or nothing. Yet the AI will use them, even if it is detrimental.
One example is army drilling, introduced with professionalism. Normally the AI cheats: armies and fleets are on minimal maintenance, yet the morale is just about a monthly tick away from maximun. With drilling the AI is fair: when drilling the morale is really on 0.51. [I am only playing/testing on VH, don't know if this genreal or not.]
Consequence: I might have taken half the lands of an AI already in previous wars, rivaled them, place my armies next to theirs, the truce is coming to end. Yet the AI keeps on drilling armies. And mothballing forts.
Wars are way too easy.
