If I'm reading this right.. and you're trying to get level 75 for all jobs on all 5 characters.. that's 70 million experience points. Even if you miraculously pulled in 6k/hr that would take you 11,667 hours, or 486 straight days of non-stop, no sleep FFXI. That's just assuming you didn't farm for gil, do any missions, quests, don't die, anything.
I hope you have health insurance or you're simply just trolling.
