Nexon: "Mechanic is a well-balanced class"

A class with 10% more DPS than others = unbalanced

A system that makes anyone with 70+ equips instantly 3x more powerful = balanced?

Potential gives the same power to all characters regardless of factors like class. Everyone gets stronger, just not in equal ways. It isn't FAIR that those with more NX gets more bonuses than those who don't, but it isn't unbalanced because every character gets the same bonuses if they put the same amount of money into it.
