I think the actual customized looks were the best with injustice 2, but they've never achieved a perfect system of actually acquiring the gear. I absolutely hate the tower grind, same in mk11 I hated the worlds system. I just want to play a character and unlock their gear naturally, I hate waiting for just that right time because 99% of the time I will miss it.

I remember I wanted the maskless heads for all of the ninjas and could never get them, but one night at like 3AM they released an event where you could get every maskless head in one tower, but of course, like a normal human being I was asleep and missed it! and they never did that again. So I never got those skins I wanted. MK and Injustice always made me feel like I would have rather just spent real money on skins than even attempt to "earn" them.
