For most games these days there is thanks to skill based matchmaking. Your brother will be matched up with people in your skill bracket and will absolutely wreck them. Then whenever you get back on you will have moved up in skill thanks to big bro and will now get wrecked until you get tossed back into the lobbies you belong.

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.

Thanks, although I was joking since I thought I was responding to a satirical post. Turns out OP is developing such game for real.

sbmm wouldn’t fix this, as skill is at the account level and changes slowly.

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.
