Let me add some of the things that I have observed about the SPS rewards. while the rewards got increased due to the modern reward pool combined into one, it seems like rewards have been capped or something. First, you can take a look on this 2 accounts by which I played which have the same rating and only played the battle around 15 minutes apart but still get around the same SPS reward despite the difference on SPS boost and the other one have 5% more bonus. Looking at the top of the leaderboard, they are also getting around as much regardless of their SPS staked and bonus. Even when matt says that it was because the reward was adjusting because of the ranked overhaul and the combining of the SPS pool, Having a bigger SPS staked and going to higher leagues should have bigger impact on the SPS reward that a player get when they won a match to incentivize them which is not what's happening right now. Will this keep to happen after the changes on april 2nd? I don't know but if having 70k SPS staked owned or delegated was more than enough for me to earn the same as the players on the top leaderboard does, then I might as well to do that with my other account that rent 360k SPS to have that 10x SPS boost.
Anyways, I would like to thank
