...further proves that George Lucas wants to screw with us. It's almost like he's cramming in shit, because he knows it will rattle our cage, and the fanboys will lap it up like a kitten on a tit.
I'm not usually a conspiracy type of guy, but that's been my thought on the more ridiculous changes for a while now. Lucas has been a control freak with a colossal ego for years.
The moment someone says he shouldn't do something - whether it be peers or fans - he makes it a priority to do it. The NOOOOOO, the new dragon call, etc - the more the fan base gets upset, the more he shows them who's boss. At this point in the history of the franchise, to me, it's the only logical explanation.
Regarding the calls; I've only heard the original. It works just fine for me.
