I like this question about fishing because I get to put my designer hat on -- and because I think fishing has become sort of a lost art in WoW these days. It used to be pretty cool to have max fishing (at least I thought it was); these days, it doesn't matter much, and that's too bad.
Will there be more incentive provided to do fishing dailies in MoP? I sure hope so...
I hope so too. I think Blizzard could incentivize the fishing dailies for MoP in a few ways.
