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

I don't see how that's relevant to my argument. If you re-read my post, I said the potential system is currently broken, it need's touching up. The problem is, the very weapon you show me probably wouldn't be a common piece end game gear if

1) It couldn't be duplicated
2) Mts didn't fund thousands of dollars worth of NX.

The point is, although the potential has a high reward with a high cost, hacker's completely took away the cost for the reward and passed it along. Now that nexon is cleaning up, it's even more expensive as the items become more limited and it becomes even harder to replicate those items.
