In other words, this is just another World of Warcraft. However, it is a nice alternative if you wish to roll-out from WoW.
Except World of Warcraft never defined or was defined by any of these things except maybe the Dungeon Finder ( though it was only added in the second expansion in a patch ), instead they all existed long before WoW in many other MMOs.
For points 1 and 4, these systems, along with many other WoW used/uses all the way down to the gameplay they existed long before WoW was introduced. What WoW did was improve on them. They made a better Auction House system, a better questing system, a better combat system and so on and Blizzard spent a lot of time and money on continuously improving the gameplay of the game. What made WOW what is it was the polish that Blizzard did to gameplay systems that already existed. That's why there's no true WOW clone out there, because no other MMO has ever come to the level of polish that WOW did, none.
For points 3 and 5. Spam Bots and that kind of behavior is common in most if not all multiplayer games, especially MMOs.
As for the Dungeon Finder. Even if Blizzard invented it, I hardly see it as a bad thing for another MMO to have it because while it is really annoying to have to spend half an hour or more shouting in general in either your capital city or the dungeon you are interested in clearing out. The removal of having to travel to the dungeon yourself get's a so-so verdict from me. Sure it's a nice idea in theory to have to travel there yourself every time, but in practice you always get into the situation where you have a dickhead in your party who will need to be summoned, and then when he leaves you will have to go out to summon a replacement.
