Nerf ulu1 spawn rate

Sorry my multi-mage farmer friends, especially those who had just set up their infrastructure.

Spoiler: This is how ulu1 looks like in MapleLegends

I'm not saying we should follow someone else's change,
but this might be a good inspiration.

EDIT:

Why nerfing multi-mage maps?

1. Multi-mage farming causes inflation, the meso number goes up, but the buying power goes down.
2. New players are forced to create multi-mage infrastructures in order to catch up.
3. The one who discovered this method is already rewarded (deserved).
4. Given some time, people who have just built the infrastructure could have be paied back.
