I feel the game currently is mostly targeted towards heavy players who play like 3-4 hours daily and maybe 10-15 hours on weekends. When we play that much, it's easy to accumulate several hundred pieces of each type of meat, making food buffs trivial to maintain.
Trivial, but I still think it's a hassle. I'd really love to be able to just "double up" or "triple up" my ingredients and have double or triple the duration.
The key is to kill animals, or TAMES, as they call it in the game. Unless you're buying all your augment capsules off the player shops, sooner or later you will have to start farming trash mobs in the exploration zones, meaning you will run into countless animals. It doesn't feel like that at low level when you're likely to be focused on the Main Tasks and spending time in the combat zones (Mt. Magnus, Labs, and Forest), but eventually you'll stop worrying about ingriedients.
