I can understand the desire for perfection, and ultimately numbers don't like, but from my eyes, there's perfection in imperfection. Purely speaking, mirage is a perfected map; it's evenness should be desired by all map creators. However, perfection can quickly turn to repetition.
As someone who plays the game for enjoyment of the map (not just winning), playing a map that, for the most part, has little to no variance for the most part, setups are same throughout, rotations are quick and easy, etc etc. You can see the disliking from my eyes if you think like me.
