You know, it occurs to me...
In D&D if you want to be a guy who is managing resources, you play a spellcaster. You need to keep tabs on how many spells or slots or psionic points you have left. (I'm one of these guys. It's fun for me to do this record-keeping; part of the challenge is using your resources without depleting them too early.)
f you DON'T want to do that kind of record-keeping, you steer away from a class like that and play a fighter or a rogue. In that case, you just need to move and attack, or use feats and skills, and your position on the battlefield is really the only thing you need to keep track of. (I tend to get a little bored in this role. If my options are basically Attack, Move, do something else to get me ready to Attack or Move shortly, or maybe use a magic item, that isn't a lot of options.)
In IH, it's looking like everyone will need to keep tabs on resources.
Maybe that's what's turning some folks off -- there isn't much of an option if you're not one of those "resource manager" type guys.
