Yup, he said it all.

I am extremely sick of him, a large part of it is that I never liked him that much to begin with - yet because others do he seems to be the main villain in almost every big story. Meanwhile Batman has one of the best rogue galleries around but a lot of them have very little development or screen time because the writer wanted to use Joker for the billionth time.

It all depends what you call big: important stories, most talked stories or big in size (numbers of pages). But I agree that there are a bit much stories revolving around the Joker and that recently Snyder gave us pretty bad ones.
