For nightstalkers to get double melee and grenade while losing their subpar super while still being able to use bones of eao for mobility is so beneficial i can't see any reason not to use it. These artifacts could be exotic though, which means for me personally they will be useless on a hunter.. I tried running some strikes without bones of eao and it was horrible.. And people complain about warlock glide? Hunter jumps without bones are so bad. :P
