Not really, in my opinion this is a very disappointing update, recycled rewards yet again
The current lot of fishing dailys are just plain awful.
Once you've completed the achievement, leveled your fishing to 525 there's absolutely no incentive to continue doing them (*)
Why ? Well apart from the low gold payout the biggest disincentive are the rewards from the Bag of Shiny Things:
Weather Beaten Fishing Hat, been around since Burning Crusade patch 2.4.0. 25th March 2008
Strand Crawler Pet, been around since Wrath of the Lich King patch 3.1.0. 14th April 2009
That's it. Two recycled rewards from the past two expansions. All the other drops from the bag are low value vendor trash.
Look at the BC fishing rewards: 4 pets, 2 Ring, Blue Gem, Fishing Line, Recipe, Hat.
WotLK: Pet, Rods, 2 Quest Starters, 5 Ring, High Value Vendor Trash, Epic Gems, (BC Hat, recipe and Fishing Line), Tiny Titanium Lockbox
My suggestion is to upgrade the rewards to Cataclysm standard, after all its a new expansion, so how about some new rewards ?
Give some reason to go back and do them.
(*) One minor incentive, it does pay out 40 guild rep.
