I think we could get the effect with fewer changes.

New skill: Attract Use a fish on the line to attract more of its kind. Releases the hooked fish (giving up 1 now for more over time, best for longer sessions) to increase that species' catch weight (on the drop table) by 100% of its base value per stack. Doesn't change weights for other fish. Max 4 stacks.

Buff chum. Now lasts 1 minute instead of 1 catch.

Cordials can be used while fishing.

New ALC "Bottled Weather" recipes to create temporary localized weather overrides. (can be used while fishing along with the cordial change).

Yes tackle box please. This is insane.

Combine patience and inefficient hooking, or add a "cancel" skill so you can purge them both at once. After you get your HQ double mooch on the line, you normally want to wait for it to expire before attempting the triple mooch to get back your catch rate.

And yeah, could we get some more info on the hooksets? Nobody is 100% sure that people are using them the right way even.
