3) YRUSirius is right. Why's every monster short legged hunched over with short legs?
4) Halfings...as stated by many...Hate 'em! Skinny legs, tiny feet, gigantic square heads? Just...where to begin? On a BLANK WHITE PAGE! That's where! Hate 'em.
5) Giants...as with other monsters, 3/4 torso, 1/4 legs...and also spindly little twiggy legs? Hate it. Their giants for cryin' out loud!
You're right! What happened to the monsters' legs? Maybe WotC is going to start a marketing campaign that legs are badwrongfun, too much of a sacred cow to slay because the game must continuously evolve?

Besides joking, I do find those excessively short legs not just unrealistic but also disturbing (see the halflings, but even a bigger offender is the fire giant!).
Out-of-proportion heads, legs, weapons, muscles are all clearly design choices. They can do what they want of course, but IMHO they should really listen to the fanbase, and current polls in those articles are really not well presented at all.
