Addiction is absolutely an issue and it's a horrible thing to deal with. A close family member to me is a raging alcoholic. I know exactly how addiction effects a person and the people around them.
Kassian also is someone who makes multi-millions to play a game and has some of the best resources allotted to him by wealth and by the players union. I don't doubt that he has demons but this isn't the same as someone in the "real world" who can't afford addiction services through anything other than social services. I feel for him as a person but as a professional athlete he has more than enough available to him to help him battle his demons.
Another one of those, since he is rich, so his problems aren't really a problem.
If you think having money = problem solved, then you really don't understand anything really.
Let's do a thought exercise, If Kassian has his problems stem from losing his dad at a young age and not being able to cope with that loss mentally, does having more money help him fill that void and fix that?
Support > money when it comes to helping people with these "issues". Our management showed their support by trying to trade him away at every opportunity, wonder why that didn't help him at all.
