Well, I'll provide a few comments in favour of the dub-centric threads:
-For those of us relying on it for the OP fix, it means likely the discussion there won't spoil us.
-There are definitely many ways to slice the dubbing issue: seriously (these seem to be their goals), comically (what will they do next?), and analytically (these are the actual differences)
-The dub is probably one of the more major aspects of the OP universe, cos it threatens to break the fandom into parts, each with a very different base understanding of the plot and characters. It deserves a lot of discussion.
