Made me platinum freaking mad.
I've been fishing fairly casual/hardcore (variating) since late 2.2 after friends often suggesting it. In 2.3 SE stealth-nerfed the desynthesis difficulty of majority of the fish that had anything worthwhile from desynthesis and as such I managed to make a small profit on my server for being among the first to notice and take advantage of it. Nothing big really as I didn't fish 24/7 and I knew an oversaturated market would just ruin it anyway (which happened anyway within a week or two because Moogle market is absolutely horrible).
Anyway I calmed down with fishing a bit, kept to getting my supra and BiS accessories and occasionally going for the big fishes for the log, doing it on a zone to zone basis to keep it easy to keep track of and at a decent pace. Nothing could go wrong right?
Well wrong, it turns out some fishes in La Noscean zones are designed to really REALLY aggravate you and boy did they succeed. First it was the Cupfish in Lower La Noscea. I thought the rain exclusive fish, Syldra, would become the trouble for this zone but boy was I wrong. Cupfish took me months to catch and I went to fish for it in its 3ingame hr window several times almost every day assuming I had time between Coil, real life and well, sleep. Absolutely horrible. But I persevered, I figured nothing else could be worse. (I started to fish for it in 2.3 and didn't catch it until a week before 2.45.)
I approach 100% completion on all La Noscean zones (and unfortunately only around 50 big fish due to my casual approach, I notice the Syldra with its Rain in Lower La Noscea is going to be a pain I think because Rain is quite rare, however when I finally went to fish for it when rain showed up, I caught FIVE in that single window and not a single one got a way. Neat I thought, it gave me hope that fishing isn't as horrible as Cupfish showed it to be.
But no. Enter the Terpsichorean in Eastern La Noscea. This crab has single handedly made me hate everything about fishing and whoever has designed fishing to work like it does. Constant fish gets away messages, super rare weather requirement and generally really rare to even hook? Terpsichorean is by far the worst thing I've encountered and I've fished a fair amount of the SUPPOSEDLY harder to get fishes like Aetherlouse (before SE nerfed it to hell in 2.4), Frilled Shark, the housing region fishes and pre-supra Olgoi Khorkoi (without FC buff). Nothing beats Terpsichorean.
And to make matters even worse, the fish guide entry for Terpsichorean claims the thing isn't even rare. Then why is it that Fog only shows up in Eastern La Noscea ONCE every 24-48 RL hours and the thing either never bites or always gets away? I'm really REALLY ******' mad right now about this crab because I've been at it for weeks, eagerly awaiting that Fog only to get laughed at non-stop. This IS NOT A GOOD DESIGN.
I've had it bite 7 times total out of 4+ windows now over several weeks and all of them have gotten away. I really really hate this thing and I hate everything about it and whoever designed this aspect of fishing needs to sit down and be forced to fish for this and some other big for two weeks straight and see how fun it is.
/rant Had to let this out after yet another fog window with no dumb crab in my inventory.
tl;dr
The Terpsichorean is literally the best/worst example of why fishing in its current form is in dire need of redesign and should be less to put it bluntly; retarded.
I mad.
