But I do own those cards. I bought them or opened them. I have 2 Alt accounts, is that too much? I don't consider myself a botfarm, yet the proposal would hurt me.

My Alts won't move up to Gold because of SPS staking requirements.

Last point - Playing in Silver and above with Bronze level cards was never hard before ranked split into 2 modes. Skill is all you needed to accomplish that. (or just Alric + Oshannus)
