I'm continually fascinated by the gaming community's relationship with EA. It's like, "Fool me once, shame on me. Fool me 37 times. . . ahh, what the hey, let's throw another 60 quid in this hole. I'm sure this time it'll be different."
I can't think of any way out honestly. You can say anything you want about EA but I'm sure they act very rationally. If despite the heavy backlash over the years they keep doing what they're doing then it must be working for them. That's the problem with these lootboxes, given how fast they spread to every AAA games these days (including single player games where they hardly make sense in the first place) it's obviou…
As for your prediction, I think you're sadly spot-on. There will always be enough whales to make it worthwhile to pander to them, and milking them will be essential for any company that cares more about making money than about making a good game.
