You actually make a good point. The bottom line for me, and many others I have spoken with, though, is that it's hard to find enough time to make a real team already, so why even potentially waste time? If there was a suspect ladder, I might have thrown something together to meet voting criteria, but there wasn't. I could have made a Skymin team for the standard ladder, just for the sake of beating into people's heads that Skymin should be uber, but I didn't feel like that would be worth my time.
I guarantee you all, however, that if this thing stays OU, we will see a significant rise in usage.
