It's at worst, dishonest... "we're terribad at math because we don't actually even play our own game" is pretty common. Coupled with awful RNG gimmicks can make events miserable for sure.Of course Inno is predatory. They may not be smooth but they are predatory. How do we know? They make use of volunteer support for a start. That's a predatory practice considering they're a profitable business.
At every opportunity they're trimming back on those free diamonds and jacking up costs. Look how quickly we've adjusted to pay-to-complete sets?
If you know what to look for you see proof of behavioural economics everywhere.
But predatory? Nope.
Truly predatory practices are what Sony & Microsoft constantly do... You want a new X-bone system? Cool, spend $500 for the console itself... oh, but the 1 controller you get is trash, so now you really *need* to spend another $100+ for a proper 'pro' controller... ah but you want to play more than 1 or 2 games? Well, now you *need* to buy a memory card, because the basic system memory is hot garbo... and 99% of our games require on-line access to really engage in, so, yep, now you also *need* a monthly/yearly on-line play pass too!
...or else companies like EA, who are not only the undisputed kings of the nickle-and-dime DLC style crap, BUT ALSO, are absolute scum who aim in-game 'booster boxes' at kids!! (and these 'booster boxes' are as pathetic as 1-use-only boosters for things like NBA/MLB games)
THAT'S what actual predatory practices in gaming look like.
