That's like saying "Because it rained on the days those two people were killed, people are only killed when it's raining."

Or let's take yet another angle: Of the three filler arcs the Daphne arc was the worst (in my opinion). And the Daphne arc was the only one where the story didn't focus heavily on Lucy. By your logic I would have to conclude that the KotSS and ESC arcs would have been even worse if not for focussing on Lucy.

But that's just mindgames... The arcs were bad because they were really badly done. The Daphne arc sucked in pretty much every aspect, the KotSS arc made every one of the Fairy Tail characters (except perhaps Mirajane) look stupid and weak, not to mention out-of-character quite often and a few more errors and the ESC arc, while it had a good base-story was just badly executed yet again. All those things are completely independant on who the story revolved around.

If the story of the KotSS arc had featured Levy as the main character, it wouldn't have changed how stupid and oot everyone else behaved.
