What would happen if maplestory remove the damage cap from 50mil to 1bil or more?

Mesos should have never had their cap raised.

I completely disagree. You can actually buy cubed and scrolled equips with mesos because of that 10bil cap. Now I'm sure you're not saying that and you just mean inflation never should've gotten as bad as it is, but that's because maplestory has no means of erasing currency from the economy. Literally everything is exchanged between player hands.

Star force alleviates it a tiny bit but it isn't nearly enough. Thing is, Nexon is so hellbent on making progress through in game means so time consuming and impossible to actually manage that they'll probably never bother actually implementing a worthwhile meso sink.
