Oh! I guess if it's got to be "stand and press a button" and you automatically got the fish every time it would be pretty dull. I mean it's already a little less exciting than facing off against the fish in a battle of lefty/righty, so I'd be happy if it were:
eg
50% chance to catch fish at your level
+up to 25% chance to catch based on full NQ gear
+up to another 10% chance if you've got HQ gear
+up to another 10% chance if you have max materia
+up to another 5% chance if you have max food
Which I presume is exactly what the Gathering skill will be used for by Fisherfolk.
