Idk I'd say everyone here gets pretty happy about RNG doing something nice for them for once. Getting the Sleeper Simulant or The First Curse or even your exotic sword is never gonna compare to getting that long awaited Fatebringer or Gjallarohorn drop or whatever. Obviously not. Although I never had to wait for mine, I got both before I even knew how good they were.
Sure, it would have been nice to get the Zhalo Supercell from an engram, but RNG decided I needed a bunch of Monte Carlos and Suros Regimes instead. I was happy when Xur sold it. I was happy that Xur sold Ice Breaker back in Y1 because I never got one to drop for me almost the entirety of Y1. I eventually got it from the Trials Mercury chest in the last week or 2 of HoW. Sure, I would have been fucking thrilled at that drop had I never bought it, but it wouldn't even compare to the frustration of never having one.
RNG sucks.
That too.
