Okay, why has Excadrill been banned instead of Sand Rush + Sand Stream? Surely, after the Swift Swim + Drizzle ban, this shows an inconsistency in the process that should have been sorted out before the ban was implemented. It's pretty clear, imo, that either Sand Rush + Sand Stream should have been banned, or there should have been an official questioning of Aldaron's Proposal, resulting in its undoing and the ban of Kingdra, Ludicolo, Kabutops etc. (or perhaps even Politoed), after which Excadrill could have been baned without question.
It seems to me that the majority of people who nominated and voted for Excadrill instead of nominating and voting for Sand Rush + Sand Stream would probably have disagreed with Aldaron's Proposal anyway; so surely this should have been sorted out before Excadrill was banned at all? Surely nobody is suggesting that Excadrill was banned primarily for reasons other than its speed? I really think Aldaron's proposal needs to be questioned pretty much immediately, because it's looking pretty silly at the moment.
(Also, it's a bit of a shame that Excadrill is no longer available as a Sand Power CB'er or as a Sand Check for rain/sun/antiweather teams, like Kingdra still is :( )
