Efrideet's has a very high impact and is a pleasure to shoot, LDR also has high impact. If you have a pre-HoW one with double down and field scout, you start every crucible round with 24 sniper rounds so that's amazing but many other lower impact rifles have very high aim assist which make them crucible killers. Like prudence and longbow. I just rolled a Violator XII with hidden hand and unflinching which should be fun to use
