The big spoiler in the Heavensward opening/trailer was a huge mistake. (spoilers obv)

Isn't the fact that your character is in Ishgard for the entire trailer a spoiler as well, since the entire MSQ pretty much hammers in the fact that Ishgard is closed off to us outsiders? SE just shouldn't make trailers for their expansion at all, too many spoilers the expansion is now spoiled.

I think you forgot the spoiler alert about the end of the main quest of ARR when they say that we are going to Ishgard that rejoin the Eorzean alliance.

I admit I only watched it once so I don't remember every word that came onscreen but all I'm getting at is that the entire trailer shows off quite a bit that is built up to in the MSQ that really any part of it could be spoiler and not just the five seconds of flashback of that "one moment," as mentioned by the OP.
