How is it an argument from ignorance when there is EMPIRICAL EVIDENCE TO BACK IT UP time and time again?
Dragon Age Inquisition says hello.
Mass Effect 3 says hello.
If you don't know what I'm talking about when I'm referring to either of those two games, then you clearly haven't done your research or haven't paid attention to the DLC release history of either or the controversies of the latter.
You're asserting that MP delays SP DLC content a couple months.
1. There's not a whole lot of empirical evidence (we'd be arguing a trend based on a sample size of 2) to support this either way, but I would posit that EC, Black Emporium, and DAI's various bug and interface fixes were the culprit.
2. Is waiting a couple months for SP DLC really that big a deal?
