Date & Time: Always
Frequency: Always
World name: All
Character name: All
Class/Level: Fisher(50)
Steps:
1. Try to fish appropriately leveled rare fishes with appropriate gear from the same game expansion (level 50 rare fishes with level 50 ARR gear)
2. Notice the great lack of gathering and perception compared to the miner and the botanist
3. Impossible to catch the higher level rare fish without the very best gear of the expansion in HQ when available and full of gathering materias to the limit of each equipment piece as well as with the best HQ gathering food you can make with the same level as a culinarian. And i haven't tried them all so maybe some are simply impossible to catch without being overgeared from a following expansion.
To be more specific, unlike the difference made in stats and attributes for fighting classes & jobs between those with 1-hand weapon + shield and those with 2-hand weapons which properly distribute the attributes either fully on the 1 weapon or divided on both the weapon and the shield (similarly with armor pieces that take more than 1 equipment slot), the fisher's fishing rod doesn't follow that logic.
Where all crafting classes as well as both the miner and botanist use a main tool and a secondary tool, the fisher is the only one to use only 1 tool, the fishing rod, but it's stats and attributes are identical to the main tools of other gathering classes and doesn't make up for the lack of secondary tool, the result of which is a very big lack of gathering and perception attributes for the fisher. This gap remain through all game expansions, forcing fishers to use equipment from the following expansion to even have a decent chance at catching their current expansion rare fishes.
In the end as a level 50 fisher with the very best HQ gear available to level 50 fishers you're lacking 82 to 96 gathering attributes and 143 to 168 perception attributes depending on materias compared to both the miner and botanist (taken from a 3 star HQ crafted Forager's Scythe/Sledgehammer) which is a whole lot (about 25% of max attributes), so the fisher is limited to about only 75% of the max gathering and perception attributes available to both miner and botanist.
