I agree, everyone instantly refers to "WoW" for everything as if it's THE only MMO every created, they many created prior, and following that use the same basis. WoW did not invent the "Raid" or "Dungeons".
Having more to do I agree would work, e.g a Rift style that can only be done once a day, or the more you kill you fill up some kind of Bar, once it's 100% that is your "Token" to open the gate etc.
Although people do not want to turn this into a more generic MMO, Such as Guild Wars, WOW, etc. But they are many good points that could be implemented into D3 to give it some real added value.
