I could be wrong but the play time and research I've done have seemed to show no crafting quests or patterns for anyone between lvls 15 and 50. I see that the alien oasis patch now has quests, but I am a lvl 37 and can't see them so I'm assuming they are around 40 or 50, still leaving nothing between lvl 15 and 40 or 50. This would be an awesome add if crafting is going to be a real addition to the game.

also, if one could level up in crafting that would make it a lot more interesting, more drops from the bosses on the gems would be a lot more interesting too!!!! I have farmed forever and only gotten 1 gem drop in almost a month. thanks!
