I'd say a +9 using Axe Fighter. While Fighters certainly can't heal themselves, mobs certainly won't be alive or remain unstunned long enough to matter.

Archers would be much better at soloing if they had the same evasion rates as their BK counterparts. I think.

I can confirm that. xD Up until CP you can kill most mobs before they even reach you because of the stun/entangle skills.

Even without those skills and evasion rate I found soloing with my Archer pretty good. I've soloed with a Cleric once too but it was definitely slow. With my Archer I can go about an hour of non-stop grind with just stones, with the stone extender thing I can go twice as long. :P And cost-wise... wasn't too bad, you'll be making profit in most cases so as long as you're going against mobs your level. Plus, because Archers don't have a lot of skills... you can save up before you buy the next set which was always nice. I save more money on my Archer than my Cleric... gained that first 100s faster.

I like clerics because they have the ability to heal themselves and save money on hp stones.. true that fighters can stun, but they only get their second stunning skill at level 43, but if u can wait, i guess it would be good to keep enemies stunned all the time...

For cost efficiency, clerics.

For time efficiency, fighters.
