you LITERALLY UNDER NO CIRCUMSTANCES could get more than 4 keys a month is what im saying, so your entire "wah i get less keys now" is 100% utterly false and incorrect.
and yes im fine with it since being toxic used to lock keys as well so its really not too different. I also purposefully avoid buying every skin i want to make sure i still have the excitement of getting one i want from a chest. chests would be boring if you owned every skin you cared about so i avoid it=P.
ive spent 1500+ over the years on this game, alot of which was phone credit that would have expired anyway, nevertheless chests/keys are still an incentive to me as a skin through a chest is much sweeter than a bought one, for me atleast.
