Is there a system in place for when my identical brother who is leagues better at your game than me hops on my account and proceeds to mop the floor with the competition?
People generally hate this though because for one it makes most games into way too serious sweat fest with everyone so closely matched. And for two it doesn’t even stop the entire reason it was built which was to protect the noobs. The elite players can just tank like an nfl team for a few rounds and go back to stomping noobs.
what does fix this is handcam anti-cheat, which makes it trivial to identify the operator by their hand movement patterns, arm size, etc.
you can review not only the match you are in, but all previous matches. full fidelity replays + handcam = a brave new world.
account sharing is not allowed in ranked. in pubs, go crazy.
