ShadowX, admittedly I haven't played any MMORPGs before, unless you count the MUSHes and MOOs of the early nineties (which I hated, by the way). However, if you're looking for revolutionary advances in Blizzard titles, you're looking in the wrong place. They don't make revolutionary advances; on the contrary, they're famous for taking a cliched concept and perfecting the snot out of it. I can't address your specific criticisms, since they're rather general, but I can say that I didn't experience any of these areas to be problematic. Course I'm a Blizzard fanboy, so that that with a grain of salt

CrusaderX, the changes since the stress test include:
-
A durability System. Armor and weapons now degrade, just as they did in Diablo. You have to pay money to vendors to get them repaired. Blizzard added this in as a money sink: without it, they feared that endlevel players would accumulate a ridiculous amount of cash, and would drive up the prices at the auction house so that new players couldn't possibly afford to buy anything on the open market.
-
The death penalty. Capital punishment has been abolished. Ha ha, just kidding! Slaughter of one's enemies is still
de rigueur, of course. No, I mean that you no longer lose experience when you resurrect via the spirit healer. Instead, you take a 25% hit to the durability of all weapons and armor you're wearing or carrying, and you suffer resurrection sickness (a 75% penalty to most stats and abilities) for a length of time dependant on level. If you run back to your corpse, there's no resurrection sickness, and you suffer only a 10% durability penalty.
-Only two tradeskills per character. In order to avoid having everyone specialize in every skill, you can only choose two skills per character to learn. You can drop a skill at any time in order to learn a different one, but if you ever decide to resume the first skill, you have to start from scratch. Certain skills--fishing, first aid, and cooking--don't apply to the two-skill limit, meaning anyone can learn them.
-
Miscellaneous details. There are now voices for most NPCs, although they're very brief--just greetings and farewells. Every class has talents. Abilities have undergone some changes.
