How Mob Avoid works

Why? Before NLC came out, I'd quit my melee character because it cost too much to repot if I trained appropriate to my level. At the same time, my NL's never used % pots to train, and it's always been profitable, even going to mobs 20+ levels higher than itself. Mostly cause it's a lot easier for ranged classes to avoid getting hit (to my knowledge, Dual Ghost Pirates are the only mob in the game that has a long range magic attack but no shortrange one). I don't know if KMS updates have made it possible for melee characters level 80-120 train without losing money every time they repot... but it does kinda seem fair.

If I still had to use Melting Cheese, I'd be getting 4000 hp for 4500 mesos, instead of 4000 hp for 2100 mesos that Ginsengs cost. That would fairly quickly make me completely broke, since I already spend 80% of what I loot training on HP pots..
