You get nine engrams the whole event. The gift in returns doesn't even reward stuff from eververse and don't dismantle into bright dust. Also, you might get 100 dust max per engram 500 (exotic) if you're really lucky. These armor pieces cost like 800 so that's 8 engrams worth of dust. With them making the bright engrams cost 2x XP than normal after they were caught throttling the XP it might take like 8 hours or more straight grinding for 1 armor piece. OR You could spend your money on a 60$ game with 35$ dollar expansion passes for what? to make the game a better place? for better expansions? You saw how the Curse of Osiris failed and was barren. They are clearly pocketing the money.
