I have spent all my legendary shards and basically poor on focusing engrams or more specifically the gambit and trials engrams. I don't have enough to even focus the umbrals. I want legendary shards dropped from playlist activities because I don't play all that often nor have the dedication to farm up nightfalls for weapons to discard. The engram focusing cost for trials and gambit is also so high that I went through more than half my legendary shards focusing for mediocre rolls and the payoff is just not high enough to warrant focusing them.
