Of course not, you put them in 50 gear.
You're OP stated no lvl specifics, just that there's "no reason to craft." I'm just pointing out there there are a few reasons to use the various crew skills. They aren't required to enjoy or do well in the game, but they aren't completely useless either.
After you hit 50, then there's the no win situation where people wonder why to bother with crafting, which is a better complaint then why bother with FP's, Ops, Pvp, etc. because those things = playing the game. Maybe there's some balancing to do, but it would seem counterproductive to MMO's to make crafted gear too close in power to gear gained from kiiling BBEG's or people would just settle for slightly inferior stuff. Kind of like Elite WH vs WH.
