Teasers sites tend to at least give you some information. People who don't follow FFXIV will look at the site currently and go:
"K, so..um yeah story? Gameplay information? Class Trailers? (This is common on teaser sites) Anything other than pictures..?"
That's why it's underwhelming. I highly doubt there will be any changes prior to just 2.0 Alpha going live. So regardless of who it's geared towards, it doesn't really do much. 1.0's teaser site had a lot more information even if it was minimal, the least they could have done was linked some informative interviews if they're treating the 2.0 patch as a final chance to get the game fully off the ground.
I don't know, maybe I'm just the only one that thinks new players would want to know know what the game is about and how we're going to be playing it when you go to a website, especially since a lot of lodestone related information will be invalid come 2.0 anyway.
