The point of the damage cap?

This was before potential locks, imagine if the great Dino made it with 120% boss dmg, sad part is this is easily done with a stack of cubes, imagine this arrow+empress dual bow with similar potential+#1 dojo gloves. I'm not even including nebulites or other gear..... Ya the gear in this game isn't broken

You can't lock lines on legendary items anyway.

Thing is that most of these items are made by using NX that the hackers have amassed, and it would not have been remotley possible without illegitimate methods. The potential system is broken and needs to be nerfed without any doubts, but as KhainiWest pointed out, the situation would not have been quite this bad this if not for the scumbags.
