No, my point is:

You said it is an "accepted authority". It isn't where I live.

I am also aware that the DSM5 is accepted in other countries as being a very valid tool for identifying psychological problems.

Interesting. I've only ever heard bad things about it from related press and colleagues. Mainly about collaboration between authors and pharma industry. Essentially advertising at the cost of credibility.

And, to be honest, for reasons like that alone I can not take an american (organization)'s stance on anything health related serious. Way too much pharma lobbying.

Anyway. Fact is, I don't believe there is such a thing as a specific gambling addiction. It simply is a part of compulsive buying disorder. Whether or not there are lootboxes with a random outcome doesn't make a difference per se; it's not about the gambling. It's about the price. Even for people with a mental problem, it is a lot easier to justify not spending 10€ on a skin, as opposed to paying 2€ for a crate. It's about the lower threshold. It's kinda like people leasing expensive cars - they don't consider the total price, it's always just the one price instance that gets considered. Even if they spend 200€ on crates, they won't think they spent 200€. They'll just think they spend 2€ a few times, and that is how it gets out of control.
