I like the new fishing system. It can be a little frustrating because I don't know which combinations I should use to get the desired effect, but that's also part of the fun. I like experimenting to see what works. I even made a little google doc to keep track of which fish I'm catching in which situations. Will it help? Who knows! There are a lot of moving parts, which was intimidating when I first read about it, but it's not as complicated as I first thought.
There are a few kinks to work out, but I think there will be with any new system. A simple guide to the mechanics would help (for example, I didn't know you had to double click until I read this thread), but I think it was mentioned that that's already being worked on. There are some quality of life things that I think would improve it a little (like keeping bait in a bsb maybe, pretty please?) but those can be subjective. And of course there are bugs, but there are always going to be bugs with new things, and those are being squashed (or being used for bait) pretty quickly. So overall, I think it's a good system. There's just gonna be an adjustment period before we're all comfortable with it.
