Why are there duplicates of each weapon on the Artificing trainer? I've compared the stats and I see absolutely no difference or no light/dark orientation. What am I missing?

The reall funny thing is the duplicate enhancements. Same exact stats at the green level, different names.

Both of the double bladed sabers have orange 27 end crystals. I'll need to check the other ones on the trainer.

I noticed that as well! I was wondering if they became different blues after reverse engineering them, but actually haven't bothered to research that through. I was thinking they would change the recipes to be different later, or remove the duplicates (and hopefully refund us the creds we spent on training them).

I read a post where it was said that later some enchants should only be usable for headslots and others for legs etc. same effect different slot only.

In response to the OP, the craftable lightsabers are not duplicates. They have identical stats (for each type) but the appearance of each saber is different. The icon representing each of the 'Radiant Blade's for example is clearly different. This just gives you a little customization opportunity without having to choose between 'better' stats. You'll notice the same for each 'set' of sabers - there are 2 different looks for each one. Str tank vs dps, off-hand, double-blade dps vs tank, and single blade all have 2 versions.
