Yeah, but those people would be easily banned/punished for breaking the rules xd
Not really, if you do chat reactions on the regular, you can earn 2 stacks of rare keys, easily. The oopsie dead did was making common keys unobtainable, but right now, no one cares about them anyways. Adding that many keys to the bundle would be just easily P2W.
As I've stated before, adding anything custom would be a bit too broken for a purchase you would do with real life money. Vanilla enchants is the limit to kits.
Also, could you rephrase your reply to the looting thing?
