Javelin (Sniper)
- The only thing going for it is the ability to see through smoke. Sniping through thin-cover is already capable with the Widow. Other than that the charge-up time makes getting headshots harder. Useless weapon IMO
To its credit, it does great in single player with time compression modifications/Adren Rush, etc. But yeah, the charge up time really wrecks it for MP. Much easier to headshot a moving target with a light tap on a Widow.
M 77 Paladin (Pistol)
- 4 rounds before you need to reload (without mods). Also only 16 on reserve. This gun is a beast, but the limited ammo really kills it. You REALLY need to make your shots count with this gun or else you lose out on its potential. The damage difference between it and the Carnifex is negligible considering you need to camp beside an ammo box to put up solid DPS. As a backup weapon it is worth while, but if you are using it as a main weapon the Carnifex would be the better choice IMO
An amazing weapon for a class that doesn't need to use its gun much (pretty much Chargenova Vanguards).
Scorpion (Pistol)
- Acts like a mini sticky-grenade. IMO useless except if you want to fool around. Fun gun though.
Also amazing for Chargenova Vanguards. Anything that lets you quickly take out Guardians or similar hard targets with minimum time wasted.
Sabre and Black Widow are the best N7 weapons.
Not sure about the Sabre, but the Black Widow was pretty stupid good in SP. Lost out to the Javelin for me, but it was good until I got it.
