Confused on my next character

Right now, I'm deciding on what my next character in CelestiaLuna should be. I may have my soon - to - be Paladin, Assassin and Treasure Hunter already, but I'm itching to try out another job now... ><

I'm still deciding whether I should go for Rune Knight (because of party buffs), or Bishop (because of healing, buffing, and even the most destructive AOE offensive skills), or maybe even something else. The problem is, the guides through the Internet are somewhat scarce, and they are not that accurate, for I'm still confused whether I should follow them or not... -.-

Please, I need help! Post comments if you have suggestions, but no flaming please! T_T
