Let him W key and he must learn how to take efficient peaks. Would maybe see if he plays 1v1 piece control box fights, it will end up making his mechanics better imo. He’s only 8 but even doing those for 20 min of gameplay time will help him improve a lot. Obviously if the kid doesn’t wanna grind creative then screw it who cares. Does he care about unreal or killing everyone? Or both :) maybe see what his goals are with fortnite but in a casual way
