I was thinking about this as well.
It is a good first step for sure 
Discovery does need sorting its not only the fact that top maps stay on discovery but other maps also.
The issue is this
When your on discovery you get players and as a result you stay on discovery more and its this endless cycle. Now im not saying that maps like go goated or the pit ect should be removed entirely but how are other maps suppose to have a chance. In all fairness ive played better versions of those maps/game modes visually and more features yet the player base dies and falls off as it never stays on discovery that long and due to the pit ect always on discovery players just play it. I think its less about choice and more about its cos its on discovery.
The 2nd issue is you have maps in genres that have nothing to do with the genre you have maps in the TMNT tab that aint anything to do with turtles. You have copies maps everywhere and its such a joke. When they was the buzz for one show mammoth within a day discovery was swamped and you couldn’t see anything else just map after map of the same copied map and the standard ones ie pit ect.
imo maps like the pit ect if they are that popular they shouldnt be on discovery for a week as if players like it they will go search the map and find it. Creators are having to battle so many things and i know some who have stopped and quit making maps and its a shame instead you have all this shady bs going on and eventually the entire eco system is gunna be filled with scum no effort maps and tbh it almost is now
Then need to ban creators and remove maps instantly when they is a vid/post anything on sm about the maps and gaining rewards ie xp or vbucks ect
Lastly i like how they have added this new rule but think of it like this all the maps that have scammed people made 10’s thousands of $ get to change the words and thumbnail and keep the money does that seem fair ? i spend a long time making maps and not all are 100% but id like to think some deffo are and i make literally nothing its crazy all because of this systems and discovery
