There has been an FAQ update, although it was dissapointing. So if you see that there are updates and are headed that way to check them out, I will save you the time and trouble. Besides Space Marines not being there (expected), this entry across several codices is the only thing that was updated.
Main Rulebook, Blood Angels, Grey Knights, Imperial Guard, and Space Wolves had the servo arm update below.
Techpriest Enginseers, Servo-arm
Replace the entry with the following:
A servo-arm is a Melee weapon with the following profile.
Range S AP Type
- x2 1 Melee,
Specialist Weapon,
Unwieldy
So the purpose of the update? Am I missing something? Perhaps we are the edge of a large update, and this was just the warm up.
