Hey there,
really had a blast with both grand campaigns just a few minor suggestions. It looks like the system snowballs - both campaigns ended around 58/59 because there was no resistance anymore - wether Frederick has destroyed all the big stacks or Austria will overwhelm with its Allies - that made me kinda sad, cause I would really lilke to enjoy the game longer...so here my suggestion - allow unhistorical options of much bigger locked garrisons, especially for important cities and capitals - additionally forts with more levels or sieges that take longer - and if the combat power of the AI falls under 80% of mine make emergency spawns that will match my combat power. Plus make units and generals gain XP faster - about 50% faster - so in a succesfull campaign, I still keep the upper hand - but the AI can also still hit back hard...
And please make 7 day turns for all games, otherwise flanking or cutting off the enemy depends more on luck than skill ;-D
This seems to be true for all AGEOD titles, campaigns mostly end way before time, due to snowball effect of combat power - so I´d love to have mods fix it or a patch with an optional option to turn on these AI boosts ;-D
