There are more supply packs available than there are fights currently so ultimately it doesn't change anything. I think supply packs shouldn't be sold from vendors, they should be rare drops only. I'm surviving only on food at the moment and the pacing has been fine, supply packs should be rare and for emergency use only.
I dont agree, forcing players to search every smallest crate for food is a bad idea.

I also tried goodberries, and they are useless. They contribute only 1 each. The 4 you get per spell contribute less than 1 bagel does.
It would also be great if spells such as Speak with Animals did not cost a spell slot when used outside of combat.
