I craft, I craft on multiple classes and I don't see this as a problem. With the ability to stock up on leves what's so bad with how it is now? There's no need to change it and make it "easier". Do you really think it'll be easier, if they were to add in new high level craft leves odds are they'll take you all over the place to turn them in not just the locations set in place now.
With rested xp and II xp boost at 46, I grabbed 3 leves, did them in gridi, turned in the one for town, picked it up again and turned it in, then checked to see if I could get it again. It was no so I synthed up some rosewood lumber til my page ran out, since over the process of doing those 3-4 leves I've done quit a bit of synths, one leve has 4 synths, and the other 3 were 7 synths. So in total those leves provided be with 25 synths. Turning in a leve gave me about 3.5k, so I'll just say all 4 are around 14k. So 25 synths, I could get about 1k a synth because of the % boost, so 25k and 14k is 39k. So with just 4 leves I managed to go from 0 to nearly halfway tnl.
Now honestly ask yourself is the leveling process really that bad? It takes maybe a little over an hour to obtain the amount of xp I did and with the amazing price tag of 0 gil to spend on materials I'd say that's a pretty good amount of xp to gain from not having to invest any gil through the market wards.
