I'm voting against.
I believe the rewards that were allocated are in the whitepaper. That's ending so we should keep it faithful to the whitepaper unless there's a big reason to change.
When staking rewards were introduced, they were needed. SPS had no other utility (except tournament requirements). It wasn't required for rewards, there was no voting, etc. We have those things now. We also have the SPS burning for DEC. We can also rent out SPS to other players. We also get vouchers as rewards for SPS staking. Getting more SPS for having SPS staked is no longer necessary.
Without SPS staking rewards, we're giving out less SPS, reducing sell pressure.
More important than any of these is that the DAO will need to provide the SPS rewards for ranked and tournament play at some point in the future. It is much more relevant to the game to save SPS for those two things.
