Doesn't sound elitist or ridiculous to me at all. A very good post. I'm not sure I want all 6 man content to be ridiculously difficult, but yes certainly lnishing mistakes or demanding more from us than sambrog did this time round.
The first boss fight at bells requires paying attention, atleast how the adds worked meant it wasnt mindless. from my experience it was much harder to do for Pugs than the actual "challenge". even if someone killed the adds and made him invulnerable it didnt create a wipe, Simply delayed the inevitable.
All in all a better mix of difficulty very few sambrog level stuff and nerf rewards. more bells level stuff rewards for that seemed good seals wise (not sure about class golds) and having some very difficult stuff but rewarding ++ so theres a nice carrot tempting you to put up with high risk of failure.
