I have noticed that there seems to be a lack of communication between mappers and competitive players. Mappers dont understand why their maps are not welcomed by them, and vice versa. Most of these reasons being that mappers carefully put aesthetic design and competitive players cares most of how the game will feel on this map. To understand a bit more the how and the why of competitive maps, i have created a prototype guide designed for mappers, that use a simple tool, called spider-view graphs to enhance your maps from a simple layout.
When completed, I hope this will help a bit the task of mappers, and so they can focus entirely on artistic process rather than map balancing.
