It was great - Lore was really compelling and connected to the rest of Azeroth with some significant ramifications. Wrathion's whole thing was great. I'm not really a fan of clumping everything together and saying good or bad, but I believe it was an overall success. Talents are great - seems like your choices matter and I like being able to change them per encounter.
The biggest let down was prob being told that Garrosh was the end-boss; didn't really want to skip to the last page before I even had access to the book.

Suppose I didnt like Scenario's - I mean I get it design-wise, they can use pre-existing Art Assets to deliver some group content that's both a "challenging" and capable of delivering a large amount of story - Sure, I'll buy into it except there isn't one good scenario they are all Blah... could be better. I mean it is a great tool to tell Lore - Thunder Isle solo and Wrathion scenarios - they are fine - but I mean ok ... Let me get this straight you have the tools to deliver better story-telling abilities and compelling game-play and I get that compelling game-play is the number one philisophy as far as design philiosophies that's pretty good. But when you push all expansion... I mean all damn expansion! and suddenly the last patch we see no new scenarios - shit son not even an update to the pre-existing rewards from H Scenarios to make them at least slightly compelling to the gear-hungry player. But what really grinds my gear ... besides completely goofing up Alliance Lore (Blood in Snow ... A Little Patience ...) is tell us whats happening around the Seige of Orgrimar - I mean hello you have a tool that gives you the ability to show us whats happening! You said you already use existing Art Assets - yet not a single new Scenario ... You said that Dalaran was above Bilgewater Harbour bombing it Show Us ... that would have been amazing! Stage 1 Creative Writing "Show don't Tell!". And you can't really say "Oh delvelopment time .. siege of org... NO! your using exsiting Art Assets and instancing it I mean the updates from Cata make the surrounding Zones satisfying for Instance play. I want to see a floating blowing up Dalaran or Tyrande kicking ass in the woods ... infiltrating Org with the Gnomes - fight to reach Org's Gate with Voljinn and Baine. Show us and don't push a feature then abrublty abandon it...

Synopsis: Scenario's by Blizzard are weird, inconsistant and a contradiction.
That is all. Mop was great.
