Yeah I was always worried about going down because I figured I'd never rank up because of it but those who tell you that you need a 80-120 or something kd are just bullshitters I held it with a 20 kd
It's purely consistent high rounds good idea by treyach as you have to be genuinely good and play long highround games without rage quitting to keep your rank it would seriously be pointless to boost to get high ranks as you'd loose them so quick
