Lowry's a pretty huge snub, but in the West I don't see a lot of obvious outrage. Kobe's the obvious one to leave out (though I have no problem with a fan vote for an exhibition game lineup being a popularity contest), but after that you're dropping Harden, Parker*, Dirk, etc. who have all been playing at a very high level for winning teams.
No matter what adjustments you make, the biggest unfairness is going to be the much lower standards for being an all star in the East.
*Good luck convincing the coaches to vote for a team where San Antonio has no representatives whatsoever, BN.
