Filler arcs between manga arcs are one thing, but splitting a manga arc with a filler arc is the worst possible thing you can do.

A great example (in a very negative way -_-) is the Bleach anime, where they didn't just split manga arcs, but also split a single fight with an entire filler arc in between. With the crap they pulled, I'm surprised that Bleach anime survived as long as it did, until it was axed.

And looking at the overall quality of the Key to the Starry Sky arc, I'm very happy that Fairy Tail went on hiatus rather than trying to force-feed us roughly 52 episodes worth of filler material.
