[Discussion] The Ecchi ruins good historys?

Fairy tail, it's started with very little ecchi, and had a pretty good story, but near the timeskip it was becoming more and more ecchi, it got a little ridiculous, it kind lost interest there.

On the other hand, I always had a prejudice against shokugeki no souma, like a anime about food with ecchi? like what the hell?, but it actually was very good, and the ecchi was basically just a inner vision of the characters when they were really liking the food and it was also used for comical reason.

So if the author knows how to use ecchi, it can be a funny and pleasant experience or a waste of potencial.
