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..

Night Lords are an exception I suppose because of flash jump; corsairs too with back jump shot.
...which leaves bowmen I suppose with no way whatsoever to withstand higher-level monsters without hp and hp potential equips.

Still for bosses like feudal lord and pink been, hp washing is the only way melees can even challenge them. Wouldn't you feel it's unfair that melee classes can (using legit means) fight bosses ranged classes can't? I always felt it was a trade off between accuracy and survivavility (the absolute most defenseless class, archers, have the highest ability to hit higher-level monster if it could withstand them. Warriors on the other hand can withstand almost all bosses but misses if they attempts them at a lower level). Without the trade-off, there's nothing stopping a melee that hits 150 to go to Horntail. This would be a significant advantage that could distort the power balance between the classes (Horntail drops are a huge part of the Maplestory economy; one that makes thousands of dollars for some well-connected, organized and dedicated losers.)

[edited] Also I have huge qualms about CWK potions (mainly because they made elixirs worthless and would cause inflation) but that's a topic for another thread.

[edited] Bowmasters and Crossbowmasters are still forced to use cheeses or milks because the % recovery isn't enough to get us through the next attack. If we tap ginseng we might be able to recover just in time for the next attack but we'd barely be able to slip in an attack. Further making the equation complex is the nature of archer's main attack skills, hurricane and piercing, which doesn't allow you to use pots while using the skill. Bowmasters might still be able to (barely) pot twice after being hit but because there's a shooting motion after piercing ends so crossbowmasters are dead if they try stupid pomegranate like that. Using pet auto-pot would still allow you to use ginseng but it makes more sense to mob quicker with cheese than to spend longer mobbing using (more) ginseng.
Night lords can use life drain and corsairs can use potions while on ships so yeah archers are again the only jobs who are forced to use expensive pots. Nexon really loves us ._.
