Fishing skillups broken?

[Shamago]

I was under the impression that it took more catches the higher your fishing got to gain skillups. At least, that is the way it seemed when I leveled fishing in wrath. The closer I got to 450, the longer it took.

This is what I have observed. It always seemed to be a set number of casts before you get a point. The recent hotfix list does indicate that they increased the casts needed past 500.

That being said, it seemed to me it's still a lot easier to level fishing than it used to be. My last point from 524 to 525 only took 9 casts.
