So I've been playing on this server for a couple months now, and I am familiar with HP washing and got introduced to it; however, it just seems so tedious and such a perfectionist-route that I actually detest it. With that being said, I'm looking to make a new character now that I've been playing on my Priest for awhile. Which class requires little to no HP washing at all and is still fun in your opinion? I've been looking into bowmasters, buccanneers, shadowers, and maybe even a paladin specifically. Regardless of the class, as the title states, which class is the most fun in your opinion yet requires no HP washing or little if anything? (Note: Not looking to create another mage).
Paladin is probably your best bet as far as no washing required from the list you provided. the above is correct but I would find trying to play a dark knight without washing to be pretty annoying since you'll want as much hp as possible to utilize bezerk safely.
You could play an I/L or F/P Mage, a Paladin, a Hero, a Shadower, or a Corsair. Now, you're probably looking for a change in play-style, so mages may not be all that attractive. If you got bored of being a Priest and didn't make it to Bishop, Corsairs probably aren't your best bet as they are absolute hell until they get to fourth job (and if you aren't up for a perfectionist style of gameplay, Corsairs again suffer because outside of NLs, they are the most funding-dependent class). So, it sounds like your best bets are the Paladin, Hero, and Shadower. You could also try a Bucc without HP washing as it's not an absolute necessity, but it does help a lot.
No class required a huge amount of HP Washing. The biggest reason why people HP Wash is mainly to survive Horntail's magic attack. 5,600 HP is what you need for all ranged classes and that's not asking for a lot. You can easily get this if you buy an Overall scrolled with Int, Zakum Helm, YAC with Int, etc.
