Maplestory "High Five" Private Showcase

I'm still kind of confused about the critical damage changes. If my min is 20% and my max crit is 50%, what's my new crit going to be? 50%? or 70% (50 + 20)? Or are they going to average it out and give me 35%?

All skills that give max/min crit dmg have been changed to just give crit dmg but I think they nerfed some values. Like SE used to give 30% max crit dmg and now it just gives 15% crit dmg.
