PSA: Clips or it didn't happen.
If you feel you were actually one shot by a full tank Nautilus as a fed Malzahar, by all means post a clip. If you feel you were actually unable to damage an underfed Riven as a fed ADC, by all means post a clip. If you feel you were two shot by a Xerath ult through a shield with an HP build, by all means post a clip. If you feel you were solo killed by Jhin as a full armor Malphite in two seconds, by all means post a clip. If you feel you were one shot by Darius Q with only a BC as Yasuo with shield, by all means post a clip.
We now have a replay system that includes clip recording. So if your story is true you should be more than happy to post the match history link and a full context, builds, farm, level and KDA visible clip to somewhere like Vid.me or Youtube to come with your sodium chloride posts on the boards.
No need to even argue the math or 'logic', if it happened, show us.
Otherwise from now on, I and everyone else should be taking all claims that do not include the fully available match history and video context evidence with the grain of salt it was posted with. At best you will prove your point, at worst your bullshit will get called out, you might get some advice on how to play better and the community IQ will go up a point. Circle jerking lies needs to go out of style, get with the program.
This has been a PSA. Clips or it didn't happen.
