Hello,
So, the fishing profession is largely at odds with the other professions, namely because everything else you can set up, and then leave it and come back whenever it is you remember to wander by once more. Fishing, however, requires 60 seconds of dedicated attention. You can hire Koda for an hour, in which they capture ~15 fish (I use 'em once a day to complete the fishing activity lol) but it really isn't the same as the other professions.
My suggestion is to add an alternative - I don't want to take away the active participation of fishing for those that enjoy it, but I want to make a suggestion for other's like myself that really struggle with focusing for a full 60 seconds. Honestly, I have to work myself up to it mentally, and then pray I can focus for that entire time. It's an ordeal.
My suggestion: Set a net.
Fishing recovery time is 30 minutes per trip, so I say that a net should take 45 minutes to capture the full xp of fish (so, 13items/26xp in Backwoods Brook). It will capture the 13 items like you could fish up with the rod, so unlike Koda who provides ~15+ fish in an hour, you *might* get 7 fish in 45 minutes, along with half the random junk that you fish up with a rod lol that would take your items up to 13 items. The extra 15 minutes is because you're guaranteed of getting the full XP, compared to the rod, where you gotta make sure to click on all the right spots within the few seconds, and while I'm usually personally lucky enough to get them all, I also often miss 1-3 items too. That said, I would personally prefer it was a 30 minute set up, but I want to be fair across the board with my suggestion :)
I really want to level my fishing up as much as my other professions, which I find much easier to do, because I can get them started, and then wander off to do whatever, come back, collect, and set them up again.
Why isn't fishing like this by default ;__;
