I came to 2.00 with 3 characters. A 50 Weaver, Armorer 50 and Goldsmith 40. The Weaver went Omni but I kept the Armorer and Jeweler just Armor and Jeweler. The problem I see is, even if I took the Armorer and Jeweler to 60 and just that to 60 (I'd be doing it with lower NQ exper but I could actually do it)
The big problem I see is, I can do it but I require more crafts and more mats to do it. Everything about HeavensWard from 51 forward reduces Material availability. Suddenly the 'casual' becomes the hard core. For me to move my Exclusive Armorer forward is going to be 10X harder than moving my Omni forward.
