Well when I mentioned Skymin had 100%, it didn't have 60% majority, it literally was voted uber by every person. That's 51 people voting to ban it. Keep in mind that during that test there were a number of other suspects such as Darkrai, Deoxys-A, N, S, Manaphy, Blaziken, Garchomp, Thundurus, Excadrill among others. Aside from Garchomp, the rest of those are all uber which means todays game is even weaker than when Skymin was tested. If it was deemed broken by every voter then, I can't imagine how broken it would be today. Here's the post with the voting results for the first test (where Skymin was banned) if you're interested: http://www.smogon.com/forums/showpost.php?p=3215668&postcount=53
