In the same boat as people who want to fight primal battles with parley?
Seriously, though, Sir Hiv has confirmed we'll actually fish up craftable/sellable inventory, not just a tick on a list and an achievement. Now it's up to me to find the profit, even if it's only like my other DoL in ARR so far, mostly just to provide massive amounts of mats (and gil savings) for skilling up.
Oh, also, now I can even say that this is
better than the fishing system that FFXI launched with, IMHO. And we know updates are coming, like treasure map stuff, and we can continue to post feedback requesting more.
