"This is the case when we see Sting & Rouge fight Natsu and Gajeel."

Sorry, but did you just use one of the most critiziced fights of the manga as a positive example? Okay granted compared to some anime-exclusive stuff it's not so bad, but surely there are better examples than this one.

Putting the example finding aside, the fights are actually the least problem I have with filler (that's how we usually call anime-exclusive stuff) arcs. My problem is that, as you already pointed out for the Daphne arc, most of the time the story and how the characters arc doesn't make sense.

In the Daphne arc Gray endangers Natsu and all of Magnolia just to remind Natsu of the village without sound, instead of just going "Oh hey Natsu! Remember that Village with the invisible people you wanted to help? Don't tell me you forgot."

In the KotSS arc everyone acts incredibly stupid. They know that Dan's shield reflects attacks back and are three against one. Do they do the sensible thing and attack from three sides at one, thus making sure Dan can only reflect one attack and is hit by the two others? No of course they all attack from the same side allowing Dan to easily counter them.

And the Eclipse arc was pretty catastrophic in terms of making sense and logic too.
