In addition to what I said earlier about Golden Krypt events being absolutely disgraceful, especially since they were very rarely advertised in the game itself, I'd have less issues with them if they'd been tied to just quirky/weird/thematic gear and skins; like the revenant skins, the Kronika-styled skins, the KL Saurian skins, uniquely designed masks etc. You know the type of stuff some people may want for fun, but nothing that's going to annoy most players in not having.
But having them tied to Liu's MK2 skin? Jax's MK3 arms? Kano's classic eye? Noob's MK9 mask? That was straight up insulting to many fans out there, especially those who'd never think to check a developer's twitter page after the game is already released (I certainly wouldn't, I don't really use social media).
Miss it that one single day it drops? Well screw you, you're waiting a year for it to return, so better not be busy that day. And have fun looking at it locked on your gear options every day just to taunt you -
"Found in the Krypt" they say, it should have said
"Found on Twitter, for only 24 hours, once a year. F**k you."
AND WORSE STILL, THEY'RE STILL GOING!!!! Stick that gear in the towers, the shrine or premium store already for anyone who's only just bought it recently. By the time MK11 was released, there was an 'unlock all' Krypt purchase for MKX, they should have done the same already for MK11 at this stage in its life, as a new release will undoubtedly bring in new fans or bring back old ones who may have returned from having had a dark-age away from MK for whatever reason (as I did throughout the PS3 era due to parenthood, so never played MKvDC or MK9 during the time they were current).
Sorry rant over
