Every class had a way to play it when levelling. Warriors absolutely had to have health potions period, unless they one shotted stuff to fill the exp bar, then used superman to oneshot the stuff that really gave you the experience. Can hit flying archers only with their exp skill flying moon. Every so often people would get the endless superman by killing enough to fill the xp bar again while one was still going. The intent was to group with a tao to heal you, as I recall. The useprman damage boost is their equivalent of scatter for levelling purposes. Warriors who use sword/blade can also use scentsword/fastblade to hit at a distance with skill. Trojans hit harder than warriors, but couldn't take hits as well, so until they got their spirit healing skill for stamina, they also needed health potions to level at all. And potions are better than spirit healing. Can't hit a flying archer at all, bu just wait for them to land and then bust out with the fastblade. If you can fastblade something to death before running out of stamina, then you can just sit down afterwards to get your stamina back and not get hit, and not have to pot. Trojans also had the most health. A switch to robot would full heal you as well, as well as the switch back. Taos REQUIRE mana potions, until they get meditation. you need to sit for a short time to get your stamina back to refill your mana. and it's still slower than potions, so in practice, you'd still load up on them. Taos can hit flying archers, but to do that, they have to usually get close enough for the archer to shoot back, and they also usually have good magic defense, so they are still hard to oneshot. Archers don't need health or mana options, because you aren't supposed to get hit. instead arrows are required, and absolutely no way to get more without paying ingame currency, period. They have insane levelling ability once they get scatter, and with skill you were able to kite multiple enemies that could really ruin your day if they hit you for massive exp, but can very rarely PK someone who isn't out of pots and scrolls, because they don't have the damage needed to oneshot, and the arrows needed to pk without that are expensive and have small stacks. Archers were for hunting gear and powerleveling others, and died to PKers. The ability to PK in one shot was essential to the balance, such that it was. Potency was put in because whale archers were whining that Trojans were 1 shotting them despite their paid for gear. This totally ruined the balance that was there. Was a HUGE money grab pure and simple. And then the ninja was put in. There skills were OP for PK, pure and simple, and was another blatant money grab. Blocking fly fro archers, so you could one shot them while they were stuck on the ground? If the ability for high levels to oneshot everyone else including other high levels is removed, then a cooldown needs to be put in on the potions. These are both very significant changes. And there's still the issue of instant gate scrolls, which are a second way to avoid getting PKed outside of the metzone. That one is not so easy to solve. So i think the ability to pk in one shot has to stay to avoid breaking the game. I do remember there was such a thing as a "melee water Tao". These were reborn options. The best one for 1st reborn was warrior to water tao, which lets you keep superman. There were more choices for second reborn.
