Pvp gear score error

So I’ve met up with this player multiple time resulting in getting one shot. The gear score is obviously wrong based on the stat of the character. Since matchup is based on gear score, this is totally incorrect and result in unfair matchup.

The person only has a weapon and 1 piece of armor equipped. This is how they manipulate their gear score to get matched with people that they can kill on T0 or T1. There is no gear score error
