The whole the fish gets away thing...

EX farming is fishing.

Last I checked, at least. If it is, there's a bunch of mounts I'm owed.

Fishing having its own bad luck protection wouldn't be a bad thing. Perhaps something along the lines of "No individual big fish will 'get away' more than 2-4 times, assuming the proper reel in button was used." Maybe a gradually increased chance to hook them, even, the more you cast within their window.
