Leveled on the lvl2-3 coblyns outside Ul'dah first, then moved to chigoes. EXP dropped from 105 to around 61~68 but kills were fast. All this done with the starting equipment. Got around 13k gil as well by doing the missions (although I already used some). Now I'm spamming LTW GL's and getting amazing EXP. Almost lvl7 now after an hour.
Huh, that's funny... on page 1 you said you already hit level 10. Now it's level 7? And oh boy, 13k gil when one piece of gear at level 10 costs 10k or more. Yippee.
