Dude, I think you didn't get my point there. Ofc it is always nice to coordinate builds, but it is just not that mandatory. Normal races always have waves, where they are weak, since they don't have appropriate towers. In addition every race has a few towers, which are incredibly strong due to game balancing issues. With the mm race you can do kinda cherry picking, so at the end mm is on average always stronger than normal races. And this is what you can see if you go to the rank lists. All top players are playing mastermind, since it is incredibly overpowered. Normal races have deficiencies by nature, since you don't want to make every race strong at every level. Therefore you are much more forced to coordinate.
