From reading the forums, and specially given the fact that lots of folks just acquired it via exotic engrams, I really question the actual benefit of having this rather great looking chest piece. For me it is good. Not THAT good. It adds a couple of grenades more to a super compared to an already 100% discipline built sunsinger. And even if you do care for the extra two grenades, you can only activate super so often (every what? 2mins if you have a great super build, that's if you don't save it for radiance), making it less of a constantly activated bonus perk. Two extra grenades every 2 min is really poor if you think about it, and that's if you activate juat right after you gained your super meter. A primary with grenadier can safely replace those extra two grenades, when thinking of constant DPS rather than spike damage. Its bonus are nothing when compared Obsidian mind when it comes to Voidwalkers, that can double or triple your spike damage output given you can build your super so much faster.
