@WWHSD - I never argued for changing how MOV works. I'm arguing it should be abandoned. I get you don't like SoS. I'm arguing SoS is a much fairer system than MOV, which doesn't weigh the differences in matches at all. It actually rewards players for having an easier schedule and punishes players for having a harder schedule. I showed the absurdity of its use in other games where something can be used comparably, like life in MtG. I've been playing since wave III and I don't remember SoS ever sucking but I guess that's a difference of perspective and we'll have to agree to disagree.
It's true that MoV does not take the difficulty of your schedule into account, but I think that it's pretty clear players in X-wing prefer a tiebreaker that is within their control, the major weakness of SoS, even if you assume it does a good job of weighing the difficulty a player faced (reasons have been pointed out that it did not do this in X-wing). If a player is on the bubble going into the final round in X-Wing, they can take a strategy to improve their chances of making the cut rather than hoping the players that they played earlier do well.
If you preferred SoS for Xwing and don't remember it being awful, you were definitely in the minority. I think the fact that posts like these come up very rarely since MoV was made the primary tiebreaker and there wasn't a big outcry against MoV early on is telling enough.
