I'm not too bothered about the battle fields but they are very handy for offloading the excess items and learning skills!
I'm not sure that infinite character leveling matters a whole lot as I don't imagine anyone would get to level 100 or over...unless you level really fast in the battlefields after the game is complete, who would have the patience to level over 50 times in the battlefields? <img src="/ubbthreads/images/graemlins/think.gif" alt="" />
