Remember when the top fishing skill was 300? Yes, you would start fishing at level 1 and every single fish would skill you up. Then after a while, it was 2 or 3 fish to skill up. Finally, standing at Steamwheedle Port or wherever your favorite place was and making that final push to 300, it was 10-11 fish to skill up. But you knew you were almost done! And then you hit that wonderful 300 and yay! You were skilled up! You would never ever have to skill up fishing again!
Now fishing's up to 525 and soon to be even more, and every skill still takes 10-11 fish. Sure there's a fishing quest, but that's maybe one point a day. That's a lot o' fish, especially if one has alts.
I think they need to prorate it a bit, considering how high fishing skill goes now. I still have about 5 alts with abysmally low fishing skill (actually in the 300 range but that's abysmal now). Make the 10-11 fish stage come starting at 525 to whatever stratospheric level it's going to be in the panda expansion.
