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.
If anything the opposite. Supply packs should be almost exclusively but broadly available from most merchants, precisely because as a general principle the player should always have a "fallback" solution to get more if things go poorly.
I totally agree. although I am generally against this mechanic in the camp. very annoying.:(
And I'm completely against you and anyone who shares this complaint.
