You know the routine. "Alpha," "things change," "10%," etc, etc, broken record...
Anyway, it's less useful to evaluate features based on current gameplay and more valuable to evaluate them based on a theoretical future state of the game where they would be beneficial and seeing if you like that whole scenario. Like "Ok, this would work if they changed X and Y, to make A useful, but then you end up with scenario Z, and I don't really like Z, so I don't think it would work."
Got it. So then question really is "should they remove actual food from the game and force people to eat each other out of need, since that's what were saying is 'realism' "
Then no. I don't think they should do that.
