Hello! This is a pretty simple and easily code-able suggestion, that I think alot of people would agree with. X-ray is a rather unfun thing to deal with, and goes very heavily against the spirit of SS13, in the sense that things should be uncertain and paranoia should be rife.
Anyway my proposal is this: Change miner 'Eyes of god' to simply not drop from tendril chests anymore or rework it to be something a little more interesting and fair, maybe ghost allhud? That would be cool in my opinion. Miners have alot of toys, and free X-ray from RNG is pretty dumb game design to begin with.
As for Genetics, changing their X-ray to just be Thermals would probably be enough, as it is currently just locked behind a bit of RNG, meaning you can get it 5 minutes into the round or never, which is again pretty dumb game design.
Thanks for reading, have a nice day/morning/evening.
