The thing that bothers me with the quick "it's just cosmetics, just don't buy it" responses is that it doesn't acknowledge the truth in how this game was deliberately designed.
It's strange to see some people who are quick to praise the game for how well designed the shooting and maps are and yet seem to think that the loot loop being a slow grind littered with sharp spikes of disappointment was somehow a mistake. It just happened that way. The leveling grind slowing as early as level 20 and not ramping up again for another 80 levels; the numerous throw away items of little importance; the large number of palette swap skins; the fact that you can receive duplicates (even within the same box); the usual F2P loot box process of hooooolding the button down to make a meal of it, trying to create a feeling of anticipation and excitement; the deliberate sense of disappointment when you didn't get what you want with the option to buy right there in the corner, offering relief; and now the devaluation of their own in game currency. A currency that you can't even exchange directly for money and only receive in random amounts or as a small trade in for a fraction of the value of a duplicate that you're already disappointed to see in your box.
All of that is an accident?
Are we pretending it just happened that way? The shooting, the maps, the character abilities being balanced -- that was all intentional and carefully designed, but the fact that the loot boxes are particularly manipulative and intended to target people who are vulnerable to gambling addiction must be in people's heads.
There definitely wasn't a clear intention to exploit mental illness, which is what gambling addiction is. It's funny how little that gets brought up. I guess it sounds less like something you can say is someone's "own fault" when you acknowledge that what Blizzard is doing is targeting known symptoms of mental illness that are present in many and can be amplified to greater degrees in some with certain triggers that, hey, this game possesses a lot of.
It's super unsavory and gross, though, so I guess people would rather blame Blizzard's clear intentions on the people they're targeting rather than acknowledge that, in crafting their game as they have, they have made several clear choices.
Acting like it's someone's fault that Blizzard's deliberate attempts to manipulate them worked is like pretending the player is in some way responsible for how well the shooting handles. The player had nothing to do with that either.
The manipulation and exploitation was not the player's choice; it was Blizzard's.
