I haven't noticed the reward bump very much but then again 2 or 3k is nothing compared to the 7-10k gold a match before the Spacelords change. I HAVE noticed that the mmr system is completely broken now, my mmr has skyrocketed into the 80's after a dozen wins or so. It's moving much faster than it used to, but the enemies are presenting the same challenge they would with low mmr so I don't know.
