I'm kind of torn on fishing myself. I like that it adds some functionality to the water throughout the world (which usually just functions as priahnnas spawning or as an annoying hazard during mining), but it can be frustrating when the line just randomly breaks (just because there is an item to fix it doesn't mean it's not a problem) and it can be very annoying trying to find bait. If I could buy bait, even at a bit of a ludicrous price for decent bait, I'd be a bit more inclined to fish; but currently, I can't vouch for doing it past doing angler quests. I really want a Pigron mount on my current character, but I'm down to 3 bait, and I'm not sure I have the patience to sit there with a sonar potion on hoping I don't blink when the truffle pops up. I think adding fishing was a great idea conceptually, I think it just needs to be updated a bit in the next patch for it to be a solid feature.
