I wonder.  Does anyone actually rest all that often?  The biggest problem I have is that I keep going and forgetting to rest because I don't need to or because I'd rather move on to the next encounter instead of camping.
Usually, the most compelling reason I have to camp is that I want the scenes and dreams to unfold.  And even still, it's rare that I get around to resting.
People talk about how there's no limitation on resting, as if players are fighting then resting then fighting then resting.  I don't think most people are playing that way.  I suppose only Larian knows, but it seems to me that constantly going to camp instead of exploring the next area/room would be annoying.
