I love SC2, I really do, it’s a great game and has some amazing tools to make custom maps. There is just one big thing lacking for custom maps, and that is the way they are sorted by Battle.net. They are sorted only by popularity, meaning people looking for custom games will allways see the most popular maps first, which are usually the maps that are longest around and best known. Newer maps, who haven’t earned a name for themselfs yet will hardly ever get noticed as they will always reside at the bottom of the list, never being able to gain in popularity, no matter how high the quality of the map is.
I found this nice article on Reddit concerning this small oversight by Blizzard, here’s an excerpt with a link to the full article..
The atrocity which is Starcraft II UMS Map publishing needs to be met with disapproval by fans, with the same vigor that RealID was met with.
Blizzard has given us a powerful tool, yet limited us in so many ways due to the current state of UMS Map publishing. The types of maps that people saw in WC3 and Starcraft will be non-existant due to these limitations, and many many quality maps will go unnoticed due to the nature of the current custom game list which is sorted by popularity. Please, make our voices heard, and make Blizzard aware of our displeasure with the current state of custom mapping.
