Adamantly- NO!
I realize that Polyhedron used to be part of Dungeon, and it pretty much sucked then, IMO. There's a reason Dungeon went to its current format- low readership and subscriptions were down. I suspect because the RPGA content was dragging it down. I think putting more RPGA content, adventures, etc back into Dungeon would be a big step backward.
20-15 years ago, when the RPGA wasn't so cliquish, isolationistic and self involved, Polyhedron was a separate publication. It ruled. They did more than just D&D- more than just whatever WotC (then T$R) just wants to pimp this month. It was a useful fan magazine back then. I think the RPGA has now devolved from a fan club into just another marketing and public relations tool for WotC. I think it is the end result of believing one's own propaganda.
There's also an issue of the modules themselves. Back when I ran RPGA events, the quality was a little shakey. Many of the modules were becoming comedic, and almost a little juvenile. More recently, Green Regent and a few Game Day modules seemed well put together, but those would be the exception and not the rule. I would feel sorry for the Dungeon editor that got stuck with the task of rewriting some of these things. Most of the RPGA modules I've seen lately seem to be linear, formulaic and at times, not terribly well edited. It's not the quality of material I'd want to see in Dungeon.
At any rate, please keep RPGA modules out of Dungeon. If RPGA people want points for the modules printed in Dungeon, let them. That's their thing. Okay. It doesn't matter to the rest of us one way or the other.
I will say that this is >just< my opinion as someone who has become disenfranchised and disappointed with the RPGA several times over. I suspect I'm not alone.
