if you could only have 1, it will be ice breaker. i think praedyth's is one of the best legendary snipers in the game, it has a good balance of stats. that being said it lacks the damage in pve to be my #1 pick. i would put black hammer in the #1 spot only because it does more damage than icebreaker and it doesn't eat up an exotic spot. i wish they buffed patience and time. let it hold 6 rounds in the mag and 8 with field scout. also let it hold 32 round in total,42 with field scout. that to me would make it a desirable choice
