A post has already been made about this, but as it has not been acknowledged, I am making another to try and bring it to attention. Class-specific finishers (such as Ionic Spear, Whirling Edge, and Fracturing Slam) and emotes (such as Stormcaller's Patience, Gunslinger's Anticipation, and Sentinel's Respite) are currently unobtainable, not from engrams and not for Silver from the store itself.
