The problem with this match is that it means that one of the two of them is going to be in the final four, which is way, WAY further in than either of them should be.
There's a difference between being an underdog and being an underdog and not belonging in the competition. Armor King was an underdog because he's an extremely minor bonus character from a fairly popular series. Sett Ra was a shitty character from a shitty game, and Aaron was a decent character from a decent, yet unknown game. Saying either deserves to win is like saying Kenny G deserves to win a Grammy for Best Rock & Roll album simply because he doesn't belong.
Ah well, I've said my part. I'm done now.
