hey guys! quick question, i was unlucky to not be able to obtain the icebreaker from xur when he was around, so in the meantime i am eying up the legendary snipers for sale in the tower (as the rng odds are worse than the actual lottery): we have "'The Final Boss" with fire damage and "The Epitaph 2261" with arc damage... my dead orbit score is too low to get anything decent out of him for now.. so any experience with either? which one should i grind for??
