Yeah, was asking me this question, cause, It don't need to attack them, they are not too powerfull for him, and last time Zodd and Guts fight, they were equals... or so... So Griffith doesn't need to bother with them, so why asking Zodd AND Grunbeld to attack them ? Cause they hurt Slann ?? No Slann is enough powerfull to settle this on her own. So, what's the reason for you ?
