There is nothing insane about it. Its a buisness, these players are merchandising gold, they sell merchindise, they bring in viewership, they attract sponsors. What is it you do not understand?
As if EVERY team that is below current top30 shouldnt have an org backing them up. If you had your way this scene would be dead.
Imagine being such a pathetic person that dignitas signing these legendary players actually bothers you.. You really want to be that person? It would serve you well to rethink your attitude.
