Just to confirm what el observed recently. From the latest hotfix 07 December list;
There is no longer a School of Fish in Elwynn Forest that like to think of themselves as in "testing," nor do they yield Peacebloom when fished. This School of Fish is no longer a part of the counterculture and will no longer give you flowers when fished.
Also confirmation on the removal of the Fishing Lure. Hopefully it will make a reappearance.
Recipe: Feathered Lure is no longer on the vendor list for the Cooking reward vendors, as it's returning an error "The Spell is not available to you" when players attempt to learn it.
And also, they obviously read el's beta thread ;) because;
There was an inconsistency in Cooking skill-ups between Lavascale Minestrone and Lavascale Fillet which has been addressed.
It requires 500 Cooking skill now to use, although from comment on wowhead this is not retrospective and was still 450 for those that had already brought it.
