A difficulty they'd have to resolve is...what do you put in there? Grade 5 nodes already have R50-70 spread utility. Grade 6 would either provide redundant yield which doesn't make sense, or it would provide unimplemented yield, which makes less sense.

It'd have to be a novel gathering experience, at that point it becomes unfair to the poor fishers...sortof. Screw fishers nevermind. Freaking grade 10 what is that. Honestly.
