Agreed. I can't speak for Exploder, but I was also advocating scrolling back the rogue's combat utility.
I don't want to see anyone sitting out in combat. I just don't like everything balanced around combat. The rogue shouldn't be a "Striker" in the sense that he dishes out obscene damage in pretty much every combat. That's the fighter's schtick (though I kinda like that the ranger and barbarian might be able to out-do the fighter under certain circumstances).
What I'd actually like to see is a "Utility" role that has typical damage output like a Leader, but really shines in exploration/non-combat situations (skill challenges?). In combat, the Utility character would be doing steady, but not outstanding damage, plus some things that are somewhere between the Leader and Controller roles. Movement (foe, ally, or self) powers or condition-inducing powers are great examples. For rogues, make sneak attack an encounter power or cut its damage in half (or more).
Maybe my idea wouldn't work out, in practice. But, it's certainly the flavor I'd like to see from a rogue, diviner, illusionist, artificer, noble, archivist, and several other concepts that have floated around over the years.
