Michael Gray explains it for us: Fishing up Old Crafty, so I can complete my Warthgate quest series. I really want to finish levelling my Paladin, but Old Crafty mocks me. In my sleep. In nightmares. Like some drooling, fanged monster.
And apparently Michael isn't the only one. Daniel chimed in to say "I leveled from 1 to 270 fishing in Instance Ogrimmar before finally giving up and finishing Wrathgate. Then I came back later and got Crafty on the second cast. Old Ironjaw in Ironforge still eludes me though." But, sadly, not all of us thought up this strategy in advance. Matt Rossi joined in with, "Wait, you're not finishing Wrathgate so you can go to the Org that's phased for Martial Law? Sneaky, I like it."
For the rest of the team -- and to add your own thoughts on skipping Wrathgate -- read on!
