Diablo Immortal PVP - NecroLancer 101: DON'T SMURF! It spoils the fun & screws up matchmaking!

Smurfing (where someone delilberately lowers his/her resonance while maintaining extremely high secondary stats), has been rampant in the game.
They do it to gain an unfair advantage against weaker players and have fun pug stomping.
TLDR: DON'T DO IT! ANTI-SMURFING!
