I would say it's the other way around. E-sport is advertisement itself and they chose not to spend money on it. Not yet anyway. Which is a shame since it came a lot of people from a lot of different games that would have made a quite decent scene.
Have you tried out zula? They have announced 100 000 dollar tournament and its coming on march. Some of the competitive teams seems to be bad, I bet you would have good chance in world cup on that game. I highly recommend you to try it out!
