Probably a Hot take but I think theTyrannotitan Hunger is perfect and other Apexes should have the same Hunger.

So obviously everybody is struggling to feed their Tyrannotitans it takes about an hour to starve. Critters unfortunately don't give enough food at least the larger ones don't which once that's fixed I think every Apex should starve within an hour.

Herbivore Apexes should also starve at a similar rate with how many berry bushes there are now if not faster.

I think Hunger and Thirst are a great way to manage Apexes without nerfing their stats. It keeps them moving and puts a focus on hunting players not just Critters. Also makes controlling a PoI very hard unless groups eat each other which with more Apexes becomes a compounding issue because of how they'll need to divide food.

TL;DR Once the larger Critters start giving an appropriate amount of food all Apexes should starve with a hour like Tyrannotitan.
