Funny you mention OmniDock in any kind of passing, because I think there might be a more implicit reason he lost baked into how DBa's new '5 categories' system works (could be less, but hear me out). In other words -
It doesn't really take account of how important individual categories can be, or one advantage being 'more' of such than another.
Everyone tunnel-visions the daft nature of the Sun Disk feat, and sure, that horse has long since been bludgeoned, but I also notice no one say 'hey, so what if endurance and stamina (or whichever ones they selected) were either A) not selected, or B) made the same category (making it de-facto 4 categories to consider instead of 5, allowing OmniDock 2 advantages each)'. For Xeno VS Anything, I even made my own version of these category charts...
with a slight tweak:
(Yes, Melia vs Aladdin contemplates this many categories. Sue me)
So, you might be looking at the numbers outlined in this pink-ish red and thinking 'well, what the bloody hell is this supposed to mean?' - and these come out to a scoring system (or ratios) that consider how much a character wins individual categories by, as well as the number of categories won. This fixes a few things about the current categorization system, one of which is that one character winning an equal number of categories to another means you don't have to shoehorn in a extra 'tiebreaker' category that doesn't mean as much to the fight.
And you might be thinking 'oh, but what if one character wins 3 categories 55:45, and the other wins one 65:35? What happens then', which... sure, but not only is that kind of tie is
disproportionally less likely to happen, but how important those categories would be to a fight is subject to the type of MU you put forward anyway.
