I know. And you dont see me going around saying people who dont like black lightsabers are dou@#enozzles and full of themselves either. Everyone has their own things they think look cool. It doesnt make me less of a fan or I wouldnt be playing the game. So get off the high horse.
For real responses, what level do I have to be and where do I find those missions referenced?
Level 50, and pretty much anywhere there is a flashpoint in general. You get those badges from hard modes -- or is it nightmare modes? Someone else will want to clarify for me, I think.
Personally speaking I don't like the mixed-color lightsabers, but that's an aesthetic thing rather than a difficulty with the canonical status of such things. They just look ugly to me. Though, the black-and-red works reasonably well.
