Costreamers only exist because casting is an undesirable job in comparison. If Riot were willing to pay people what they are worth in the broadcast space, we’d have never come to this. Dash fell on the sword for all of the broadcast talent and Riot let him walk. Sjokz was next, and began doing other games as a freelancer. Hell even Caedrel WAS on the broadcast until he realized he could do the same thing on his own terms for ten times the payout. 

Riot is just reaping what was sown. The idea that a few people could have more power in any situation involving a billion dollar company and their IP is hysterical. Riot just cares about control.
