At the time of trails and iron banner I had 2800 grim and I've beat teams that had maxed grim or over 3000 so I say it's bs cause just bc u got low grim doesn't mean you suck or you don't know the game it means sometimes you have a job or family and can't spend hours and hours on in to look on YouTube to find all ghost so I say if your good at game I can tell by the way u play regardless If ur maxed or not I've seen crappie players that are maxed and I've seen good so that's what I think
