So I've been making the seafood mag feasts for my guild's raids and I'm finding the lavascale to be something of a mixed blessing.
Boon is that I've got seven 85s so getting the @#$% fish is a great way to level fishing while being productive - queue for instance or BG and start fishing away.
Bane is, of course, the fact that there's no pools for them and even at the 30% rate for max skill you're talking 60+ casts for just a stack (enough to make 10 feasts).
