Being innovative doesn't mean it has to be new to the genre entirely. Those are features that were not found in World of Warcraft until now and they attract attention from players who enjoy that sort of thing.Except it isn't innovative at all.
I believe OP was talking about new, innovative things to gaming and the genre in general. You know... sort of like they pulled out in the initial release and following expansion, and not so much afterwards. If you can name one new, innovative thing they added in the past 2 expansions (MoP, Cata) you deserve a cookie. I'm talking actual gameplay wise, and not system mechanics, because be honest, there really isn't. The last thing worth even honorable mention is the implementation of heroic mode raids (WotLK), and that was really just the next step up from heroic dungeons already added in BC. Vehicles and phasing added in wrath might honestly be the only real one since BC, and those ones had very mixed results. (Phasing while more a system change had huge implications on gameplay as well, LFR, LFD, and CRZ are system changes with minimal changes to gameplay and quite a bit of negative feedback.)Pet Battles - Easily recognizable as a bad pokemon rip-off.
Scenarios - Easily recognizable as a terrible easy dungeon.
Brawlers Guild - While I approve of this to a degree, in game monster arenas have been in games for quite a while (FF7, Overlord, etc, etc).
Treasure hunts - Treasure hunts are certainly new and innovative... Something never seen in history or games ever.
Farms - A glorified bad rip-off of farmville and all other said farming simulators?
Dynamic legendary progression - What a good way to spice this up... did Blizzard actually say this or are you just making it up yourself to make it sound better than it is?
I didn't realize these were all in game prior to Mists of Pandaria
I pretty much agree with OP. While his presentation is a bit lackluster, pretending he doesn't have a point just because of such is ignorant. It's quite clear to anyone involved with WoW over the years that they have not only produced less and less innovative content, but they have slowly made things easier, clearer, and more open... which isn't completely a good thing.
