That would mean no resting in a long dungeon or other underground area.
I know some D&D fans would prefer that, but what's good about the current design is that players can choose their own difficulty level by how often they teleport to camp. A newbie might need to do it several times before reaching the end of a big dungeon. A more experienced player might be able to make it all the way to the end of the dungeon without resting. Larian can make dungeons any size they want, without having to build in resting areas or design it for some "average" player.
I think the worst thing about the camp system is that it's just not explained in-game. The main character basically has a ring of teleportation to a specific domain and back again. So just explain that's what it is! Or some equivalent function related to the tadpole.
+1 limiting fast travel just means you spend more of your precious time on mindless running. It's a good thing you can choose either to get rid of the mind numbing running or play a "difficult run" and not use fast travel. Player's choice.
