You know, I am all in agreement that this race wouldnt work in Midnight's desperate need to eat, and gather supplies. They dont need to eat. It'd mulch a big part of the atmosphere.
Honestly, though, no adventuring party I have EVER been with has ever had this as a recurring theme. My Necromancer is about to become a Lich and have a list of immunities far longer than the Warforged list, and yet, no one is complaining about that...a 5th level spell, "Kiss of the Vampire" turns me into a vampire now with all their immunities for an extended time frame, and no one is saying I ruin all encounters, or poison or hunger are worthless. (They are, but so?)
I dunno, I dont really get the objection. They dont eat. Ok, my response is so what? You want to challenge a party with a barbarian or druid or ranger with hunger? It just seems silly. Yes, they dont eat, but you can just take a couple of liber mortis feats and be immune to eating, sleeping, light fort and fatigue. So I guess if these things are so all fired dangerous and thought provoking, WOTC shouldnt have made the Tomb-Tainted Soul line of feats. My Necromancer has the feat chain, and my DM isnt the sort who actually pays attention to anything, and none of them has ever been useful anyway, so obviously it isnt something most people take much into account, because it doesnt appear broadly useful.
It'd have to be a pretty grim, pretty low level game for the things we are discussing to matter at all, and I cant imagine PC's with DMG style wealth levels to ever "go hungry".
I enjoy hearing the objections, though, I just dont really get them. When I looked at the race, my first thought was underpowered compared to humans.
