Respectfully disagree. To market for the TCG as a whole is to promote on steroids. As you said, that was Wave's tasking at one point. And as you point out, the position no longer exists. I wonder why that is?
Of course all of the TCG promotes, otherwise they would not join less it was for simple defensive purposes, i.e. slow it down or derail it. Wave has and continues to beat the drum louder than all else. And rightfully so as they have much more at stake. And relatively more to gain.
