It came up in conflict corner that “unless” doesn’t always make sense to transition into the 2nd half of a justification. Here are a few other “contrast transition” words that might help people out.
unlike, although, except,
contrast, the opposite,
in contrast, on the other hand,
on the contrary, rather, yet, but,
however, nevertheless, unless
I’m not sure how these will work with the justification process, but options are mostly a good thing.
