Yup,yup!

Yes,in LF I want to level up all my characters because it is indeed an army

it can be quite exhausting

THe only thing I found to help me a little though is when I have the EXP eggs,in LF3 and I may have few characters that they're level is unsatisfying,you know,when the guy in the Mage Guild helps you to spread the exp points from the eggs through all the characters,I am giving to my party all kind of boosts for maximum MN + intelligence seminar of course, and use the rest exp eggs I have.For example,when I took Vanina,because I just couldnt do all the work to level her up (...) I used some exp eggs on her and from lv 10 (or so) she was in lv 69 in no time ( and I STILL had a hard time winning with her in the Arena

)
