That wall surface isn’t normal.
Ya got that right. 
Seems to be a similar issue to the below thread.

Strength Settings
I have higher values cause this is ABS and its taking some punishment when in use. Even with these higher wall and infill settings, with a moderate amount of force it snaps across the horizontal direction. Still stronger then PLA though.
Think the higher wall count or infill is hurting here? @JonRaymond
