I think the new food mechanic is definately better than in the previous titles. It's a great system, but it definitely needs some tweaks as it can be ignored completely after certain game-progression. Basically as you get horses, your carry limit grows exponentially, and as your carry limit grows, you can get so much food that it can be enough for 2 years. Whole sieges, campaigns and battles don't get effected by the food factor at this point. There was a devblog which was just about the food mechanic. I think fixing the food mechanic would help the snowball crisis greatly. Because at this rate, food is not a concern neither for the lords nor the player. I'm not expecting the foraging parties or scorched earth mechanics in EA, but simply hard caps or tweaks might help with the issue itself and it might improve the snowball issue for now.
