I found this over at El's Anglin'.
With WotLK and patch 3.0x the number of catches needed for each skill point will be going down. Quite dramatically down as a matter of fact.
Here's just the top end of the table:
Skill level---->Number of Catches
290-300--------> 3
300-345--------> 3.5
345-375--------> 4
375-450--------> 4.2
This will be a very nice change from the current numbers:
Skill level---->Number of Catches
265-300--------> 6
300-340--------> 10.5
340-375--------> 11.5
As an avid fisherman, I have to applaud this move.
