Scout Rifle: Aries Nemesis X4. IMO its the only lengedary scout rifle that can compare to the raid scout rifle, Vision of Confluence. Auto Rifles: Either Grim Citizen from the Crucible QM or Shadow Price from the Vanguard QM. Hard to go wrong with either. Shotguns: The Commedian. Judgment VI from (IIRC) New Monarchy. Sniper Rifles: I wouldn't waste time with these unless you have an exotic primary or Heavy weapon you just can't part with. The legendary Sniper rifles are good...but the raid sniper (Praedyth's Revenge) and the exotic sniper rifles (Ice Breaker and Patience and Time) are some of the best weapons in the game. Since you're going for a legendary primary right now, I'd save that slot for an exotic if you want a Sniper rifle. P&T if you mainly play PvP. Ice Breaker if you mainly play PvE or a combination of both (and can only pick one). If you're PVP and decide to eventually go with an exotic primar (cough, Suros), then good sniper rifles are: The Final Boss, Epitaph 2261...and ANY of the Queens Wrath snipers. Either the legendary (The Supremacy) or the 267 attack rare. Both are very stable, very accurate, and hit HARD.
