That deck just isn't very good. It has a mediocre level of power in comparison to every other deck. With Null Rod losing attention, it just ceases to be as bad.
You're dead on here. The deck is, if nothing else, horribly inconsistent, even relative to [other] Workshop decks, and just plain weak when it tries to be consistent. mrrieff has had alot of success with the deck, but it doesn't resemble the type 2 derivatives that I think you're thinking of to matter in this discussion, and even that deck is weaker than TMS or Stacker in alot of cases.
I think that there is room for improvement with regard to T1 modular decks, as they haven't been explored to the full extent. Null Rod is the main reason for that.
Having that said, I think that Modular decks can be a competitive deckchoice when the amount of Null Rods decrease. I have indeed had very solid results in highly-powered metagames with versions I think are not optimal yet, although improving each time. When the T1 community will take the decktype more serious and will help to improve the deck, a lot more is possible than its current status. The reduction in Null rods is required to warrant that attention however, as it is the bane of this deck.
More on topic: The dicsussion whether the reduced amount of Null Rods is correct from a theoretical perspective, is interesting. However, fact is that currently there is an actual trend of playing less and less of them. (leaving aside the question whether that
should be the case). Maybe we should also discuss more the impact that fact has on the metagame. And maybe I should return to my beloved Ravagers soon
