If the exploits from those features were what they are complaining about missing, why are they also complaining about exploits?
With every game you have two basic camps -- supporters and detractors.
Supporters often get labeled as fan boys because they like the game. Detractors, or complainers, often get labeled as whiners because everything isn't done the way they would do it. They want their old game with all the new graphics -- basically.
People that don't fit in either camp often bring legitimate gripes and praises to the table. They are able to see both sides and often explain themselves with more ease. They don't just state X svcks. They can explain why it's a problem and its effect on gameplay.
My previous general statement was directed at everyone who can't "immerse" themselves in the game. They're missing something. They often support their sentiments with references to older titles. They have trouble appreciating new game mechanics.
