Crafting is a great part of this game. All the DoW and DoM seem to forget where they got their gear from. Without the crafters they would all be wearing Weathered Gear and Skull Eye Patches. All the great folks that are dedicated crafters really enjoy the part they play in this game. I will agree that extra content needs to be added for the crafters, which I'm sure will be coming with the added "Companies".
Imagine if you could only Battle solo, and all you could kill were Star Marmots, over and over...
But aside from that, the pace at which Crafters can level is pretty good. I'm sure SE didn't anticipate that 1/3 or more of players would want to be dedicated crafters. There is no requirement for it really. The amount of gear a high ranked crafter can make is crazy. Also, unless someone NPC's all their stuff whenever they are finished with it, that gear stays in the system, to be repaired and re-sold to lower rankers.
Great system SE, looking foreward to new crafting content, in the near future.
