Best special weapon for Blightlords?

[Zephaniah Adriyen]

Okay, so. I own Blightlords. I've been running a squad with a Reaper Autocannon for forever now, but I'm not sure I wanna keep it that way. I still have the Plaguespitter and the Blight Launcher, and I'm considering switching to another one, permanently. Which of the three is better?

[Zombs]

Blightlauncher imo.

[Wolf Lord Loki]

As much as I want to say plague spewer I think it won't get much use

In 10 man squads you want 2 Blight launcher & 2 flails. /2 for 5 man squads.
