I just got engineering IV, and I was wondering what is the fastest way to get enough exp for Droid Engineer. I made muzzles to get Eng IV, and I have been making bone armor after I got Eng IV. My only goal is getting Droid Engineer, so which is the best way?

I have been making Clothing and Armor Crafting Devices.. they give 65 exp per. And I make three at a time using hot keys for my crafting devices. It seems to be helping me. Hope that might help ya out.
