Please fix it. It is ridiculous that I wear skill-up gear, eat skill-up food, and cast enhancing magic spells non-stop for 30 minutes and get 4 levels. In 6 hours of Aby worms, I cast enhancing spells every chance I could and went up 2 levels. An MMORPG game pretty much sucks when you spend days of sitting alone casting spells in the hope of capping one of your primary magic skills. This isn't like guard which is a nicety to have. But, not a deal buster.
I hear game 'balance' all the time from the developers. How about some balance between tedium and actually being able to play a job and get reasonable skill ups?
