The official trailer to 4.3 & The Dragon Soul Raid is simplely a joke and bad one at that, if you don't believe watch it yourself.
Now look at someone taking some voice files from the Dragon Soul Raid and putting them over the trailer how much better it becomes.
And for a completely different direction that is still better than the original.
I guess what bother me about this is, over the last few years I have found the best places to show friends Warcraft and try to explain the story to show them the trailers from one patch or another to show them where we are who are the main players. If we are going back to the style of 1.10 the Weather patch maybe Warcraft is dying.
