Why does Riot limit the number of Hextech chests you can buy over a 24-hour period?
If you look back at the League of Legends business model post, one of the tenants is ”we want to add content that excites you when you first hear about it, feels good when you buy it, and leaves you glad when you look back, even months later."
The part of ”leaves you glad when you look back" was a major factor when adding in the limit for Hextech chests, as we wanted to do what we could to avoid buyer's remorse. We've all heard stories of drunk purchase regret or a kid getting ahold of their parent's account and racking up hundreds of dollars in microtransactions in a single day. Our goal is for players to feel good about all of their purchases, and these limits help ensure that as much as possible.
We are also concerned with fraud, as we didn't want someone to steal your account and spend it all on chests. I know what you're thinking ”But Rito, someone can steal my account and just buy all the skins!" – while that is true, it's a little easier for us to interpret the intentionality of skin purchases versus the randomness of boxes when rolling back fraudulent purchases.
Since the system was implemented, we've been monitoring how often players hit the ceiling, and while some players do hit the max limit, it is relatively rare. We'll continue to reevaluate what the upper limit of chests should be, so please share any thoughts you have on this.
