They've talked about allowing you to drop Tiers after a long series of losses vs other people in your same division or below. Inactivity is the only thing right now that can cause you to drop out of a Tier.

If you really dont think you should be in Silver V, go ahead and wait for your account to go inactive, then start playing once your in Bronze. Since at the moment you cant drop from playing alone.
