So, I main a hunter. I have a titan and a warlock that I've dabbled with but both low level. I intend to pursue my warlock next and as it turns out, I got Heart of the Praxic Fire from an exotic chest engram I bought yesterday.
So, no disrespect, why do people love this piece? And how can I best use it? (In 11 levels from now when my Warlock is a level 20)
Edit: Thanks everyone for all the helpful and specific advice. I look forward to trying this out!
