The reward scheme for the Masternode should be higher than what the current staking percentage is, or else its not worth it to have a change. If you have to lower the regular stake percentage to offset that increase for the masternodes that is fine. But dont make us upgrade to masternode and still get less percentage than what we are currently getting.  Also it should be easy to switch to masternode. Please post detailed instructions on how to do the upgrade to masternode when it becomes available.
