Hmm... after looking at the official post in more detail, I don't see anything about honor gains being 3X

My friend in Vent that tipped me off to this definitely said experience and honor was boosted by 3X for linked accounts, but it looks like he was mistaken.

Well, crap, that had me excited for a couple hours as I pondered the possibilities. Sorry if my original post was in error about assuming the 3X applied to honor as well. :S
