C'thun true form is absolutely monstrous.

IMO, that wasn't a red herring. I think they just decided that would not be a compelling final boss so switched direction.

Anyways, while his story development at this point doesn't point to him being the last boss, this is not the end of the story as Watcher stated. And it may be a large story, not just filler, judging by "fixing spriests in next major patch" statement.

Personally, I hope the next xpac is one with a definitive large evil entity like an Old God. I like WoD's story so far (yes ik I'm in the minority), but there's something to be said I think for Cata's story style. Even though it had many issues too, you were always fighting to work your way towards Deathwing, the Old Gods and his minions.

I like fighting Archimonde, but that came somewhat out of left field. And its a complete unknown what story is after this. (Same with 6.0). Even MoP had that issue. I really liked the story but it didn't feel enough like we were building up to something larger imo.

I want a progressive story throughout an xpac, not 3 individual plots.

You cannot say Blizzcon is a lore source however.

I always had some problem in grasping this part. It means that C'thun and Yogg-Saron "deaths" weakened the world, or the bonds dividing the physical realm from the elemental one, giving to Deathwing the chance to break them apart?

He keeps quoting that old gods caused the cataclysm which once again was a stupid comment from Blizzcon. The old gods had NOTHING to do with the pre events of Cataclysm. All of the blowing up was due to DW himself. This is a prime example of why you don't take Blizzcon statements as lore. All of the eruptions etc were caused by his emergence from Deepholm through the Maelstrom. They were NOT caused by yogg or cthun dying.

Don't take statements during the Lore Q&A as lore?

Probably.

Except that's lore until Blizzard itself doesn't state differently. You have no authority to decide anything. You can only decide the lore to be good or bad based on your personal views, not if is canon or not.
