You're perfectly capable of a three second Google search, so you'll need a far better argument then that. Besides I used to source my information frequently, but members choose to say that, despite sources (from Todd Howard's or Pete Hine's own Twitter even) it ain't true. As such I've stopped posting sources and will leave it for members to find what I was able to themselves.
This second desire for a source would require me pedaling through pages upon pages of threads to find the numerous polls and topics where the majority of members were opposed to the idea. Until Bethesda fixes the search function, I ain't doing that.
By the way, this "give it a chance" and take everything on blind faith is garbage. It's precisely why developers continue screwing over their fan base. I'm perfectly in the right to voice my opposition to the implementation.
I gave Bethesda a chance with Skyrim, I gave DICE a chance with BF4, I gave Ubisoft a chance with Assassin's Creed Unity. The worst thing a fan base can do is what you're suggesting.

Where are you getting this information? I've opened multiple links and no where have I seen that it's for written lines of dialogue.
