As I said, they made fisher in 2.0 at a means to relax not to fish massive amount of fish in a short time. Also your list on fishing actions looks outdated or incomplete, we have Chum that drastically shorten the waiting time, Patience and Patience II to use the Hookset action to catch more HQ, and Fish Eye to get other "hidden fish". If you just want a skill or something to catch 3 fish at the same time with a rod you take out the real part of fish in my opinion. Although i would say that I want spearfishing back to use as an offhand.
