Ok so I had the opportunity to play through SOO at my brothers house on one of his many alt characters...
The instance is just largely a rehash of Orgrimmar.. and as for the part in the MoP continent, its a rehash of a zone..
Whats Blizzards problem with rehashing everything they can and claiming its new content? This is getting upsetting that they do this with every damn expansion now. They have more developers and more resources working on WoW than ever before, and they come up with "new content" like this? They even used a PvP faction boss as their last Raid boss for their last Raid.
From a lore standpoint, and an artistic standpoint, i think they have started to run out of original ideas to breathe any new life into this game. I will be trying Warlords of Draenor out only because I loved TBC and we get to go back to the world that Outland originally was (which I think is awesome), but you have to admit, they took old ideas and continue to rehash stuff any chance they get.
I love this game, but man they need to really think outside the box if they want to captivate and bring new players into the game.
