It would be nice if Fairy Tail could be switched to a schedule of one episode every two weeks instead of every week. That way the animation team would have twice the time per episode and the quality would probably be much better and they'd also pretty much eliminate the need for filler material or breaks, since most episodes cover two manga chapters.

Unfortunately that is just a fantasy, unless a second series with the same age-rating would do the same so their episodes could be aired alternatingly on the basically same timeslot. But as soon as one series end and the other continues, that'd be a problem for the TV station, so it won't ever happen.
