What about doubling the number of monsters on each map? It would be much easier to mob, level up and drop items. It also looks super cool when you mob dozens of monsters without running around the map so much.
We'd rather not increase any mob spawn, and exp-wise is not really needed. We already removed the level difference limit that renewal introduced, making experience a lot easier, and not limiting MvPing the only reliable way to level up :)
This was mentioned somewhere before. Most agree that not only does it make cash farming completely overpowered, but makes certain areas like bio4 imbalanced/harder than intended. The only one who doesn't agree is Psor, so go figure.
