Oooh i was wrong.
I don't like the idea of having to pay more food to move around, even if it makes sense since there are more mouths to feed. Getting rid of followers would be nice, since you don't have much control about who joins. You just kinda say "yes" to followers wanting to join, and only afterward do you find out what those followers actually are.
(But really, convoys of 60+ are not at all "doomed". I always finish with more than that.)
