Let me get thsi straight:
You can craft to level 150 with any character, any class... But as an artificer, you can get to that earlier... And that is bad? I don't see the problem.

What you do with your characters is your choice. If you specifically build a human arty to get the most from crafting, more power to you. It does not affect anyone at all negatively, so I see no problem.

If you buy the arty, then you know you can craft more advanced stuff earlier, but in the end, you craft the same level of stuff as anyone else.

The only real boon would be if at 150, there was a failure chance in crafting. An arty would eliminate that.

But if 150 = 100% for all shards, then there is no serious benifit for speccing an arty for crafting.

This is like someone who is speeding down the road while you go the speed limit. When you get to the light, you are both stopped. So what is the point of speeding or going slow?
