Are Heros Infused?

Huh? Huh? Are they?

I'm sure this has been answered before, but anyway: http://gw.gamewikis.org/wiki/Infusion

Unfortunately, this article is contradicted in the mission guide for iron mines of moladune: http://gw.gamewikis.org/wiki/Iron_Mines_of_Moladune

So at the moment, the likely answer is 'yes' but it doesn't seem to be a sure thing...
