i doubt anyone would agree with this but hey I'll throw it out here:
Let's say highest crafting possible is 200 for this example. Artificers get at least +10 to crafting at level 20 so that's level 210. i think it would be pretty neat if there were bound shards that were pretty sick that only a maxed crafting artificer could make. Not sure what they would be exactly but something that would make others say, wow that's pretty f'ing awesome.
Personally I have no issue with a class being granted better crafting abilities, namely the new artificer. Personally i have no problem with them having things other classes don't. this happens with all classes to some extent. I'm certain most people would say a multitude of four letter interjections about this idea, but I still think it would be neat.
