I did for a while, everytime I got matched with a 100ms russian I could hit every shot or got fucked before I had the chance to see him. interpolation does work very poorly in cs, and no, faceit doesnt magically fix it. Instead, it makes the issue worse by enabling their server side anti wallhack, which hides players until you peek them -> random chance decides who sees whom first.
This just explains why I dont think br games are incomparable to csgo. The game format of cs itself is superior to br, obviously, but that doesnt mean that 1) csGO is superior in every regard or 2) br games are not competetive at all. they are, to a lesser extand maybe.
