If possible....(remember the use of the word "If,") try getting a wizard friend or a Sader/Knight and go MvPing. That's how I level my Creator since AD is a little too expensive for my taste to use on other minor monsters. A Hunter should be okay as long as there's something to block the MvP's path (hence the Wizard/Knight/Sader suggestion).
But idk...you might not like it since it's VERY competitive....
