There I was, sitting watching it:
"Okay, a third of the way through the video and all we have so far is a misshapen human and an orc fighting."
"...Halfway through the video and it's still just the two of them fighting."
"Oh look, a panda... now all three are fighting."
"Wow, it's almost over and still nothing but fighting. I guess PvP is all this expansion is going to offer."
Compare that to the Wrath of the Lich King Cinematic Trailer where there's storyline! Introduction of the bad guy! And, to use current net slang, all the "feels" anyone could want out of a trailer.
Not to mention, watching it again, the voice acting and the music is so much better than the MoP one. Even after all this time and so many views, the WotLK one makes me grin and gives me chills, it excites me, it makes me want to play the game. The MoP one? Makes me want to go back to Northrend.
This is on top of more MoP bad news: Alchemists will no longer be printing money, unlike every expansion before this one. And I have 10 maxed alchemists. What in the world will I do with them all now?
Hopefully MoP will be better than Cata, though even with that low of a bar, I'm not holding out much hope. The trailer just comes off as so silly and pointless to me.
On a related note, since I have a second account, I was able to roll a second DK. The DK starter quests and zones are still so amazing. One of the best experiences in the game. So cool.
