SUGGESTION: Make all fish used in Cooking/Alchemy available as retainer ventures.
Fishing is almost certainly the most unrewarding of the gathering jobs. With tons of fish that serve no purpose outside of desynth and a healthy dose of RNG regarding what you catch, it really shocks me to see that a Fishing retainer can't even get the fish needed for cooking in Stormblood. What incentive would anyone have to make a retainer a Fisher in Stormblood?
Look at the level 63 retainer venture:
Lv. 63 Sea Pickle
Now this could be an error on Gamer Escape's part but... they show the LEVEL THIRTY sea pickle as the reward a level 63 venture. Sure it would be a fine choice as a level 30 venture (of which there are none btw), but it makes no sense for it to be level 63. I'm going to assume however, that whats actually awarded is the new sea pickle from spearfishing.
And now with Stormblood, the fish acquirable via retainer ventures are so few and many of the cookable ones are missing while a few of on the retainer venture list have no use at all. Why are Botany and Miner retainers so useful in what they can bring back but Fishers aren't anywhere close?
If someone takes the time to level fishing AND a fishing retainer, they should really get a lot more out of the investment than they do.
Fish that should be on the retainer venture list but aren't include:
Horned Turban
Yugr'am Salmon
Yanxian Tiger Prawn
Swordtip
Corpse-eater
River Clam
Amberjack
Zekki Grouper
River Bream
Ivory Sole
Motley Beakfish
Please consider adding these missing fish to the retainer ventures list for Fishing retainers. And please move the level 63 Sea Pickle venture to level 30 since it actually is a level 30 fish used in level 30 content >.<.
