And once again, a confirmation of the crafting professions we were originally told. It looks more and more confirmed that the "rune crafting" profession was a case of the interviewer mis-hearing, mis-interpreting, or just plain not knowing what was going on.

Rune crafting could have been enchanting, that's the enchant system Rift uses iirc.

My character will be known for crafting poisons!

I don't see the point of this, like they actually care what profession you will take. I know I wouldn't.

Marketing - building hype - a weekly nudge to keep people talking about the game.

Just so people will talk about what they are excited about. It's really not that big of a deal.

Ya that interviewer was just straight up wrong. I never considered the possibility that he was right.

THe point of these is actually for 2 reasons, sometimes the questions get you thinking about what they are planning to do with so and so content. That and ZOS actually likes to interact with the community, they post the best answers on the Tamriel Crier. I find it fun
