I think 80 would be my limit. I can't exp til 85 for personal reasons.
If you're interested in bot-powerleveling after lvl 71 let me know. Please when letting me know, give me your exact example:
"Hi Lain, my archer is 60 and I want him 80, tell me time and price, thanks". That would ease the things very much. Thank you.
Also, don't forget to mention vitality (best time to give me your account is after wednesday's maintenance (boosts VIT to max), equipment time (I can't exp your char from 60 to 75 if your time on equipment is 1 day), and class)
