Just out of curiosity, are you leveling the LI's to 31? More often than not, when I first identify a LI, it doesn't usually have much that I would want, but when you level it up and reforge, you get to add legacies. That's when I end up finding the ones I need. I always will level them to 31. That gives me three rounds of reforging, and a better chance to find one decent legacy to pull off when it gets deconstructed.
If you're not sure how to do this, just slot it in your LI panel, but you don't have to equip it. It took me forever to figure out how this stuff works (hopefully one day I'll actually know what I'm doing!)
I hope this helps!!!
