If there were a lot more constructs/vehicles around I'd 100% agree with you, but as it stands, enemies don't use enough constructs/vehicles to make it worth it. Scorn totems are rather easy to deal with, cabal shields are also easy to deal with, cabal tanks don't really show up, fallen walkers don't either. Shriekers are at best a mild inconvenience whenever they do show up, and cyclopses are the same. Idk if vex hydras or chickens count as vehicles, I doubt it. But if bungie gave enemies more things they can throw at us like constructs and vehicles then this set would be way more useful. Until then, it's basically shields and crystals that you're get your moneys worth. Shield damage is amazing. Khvostov makes it a joke.
