Zeffo Guardians Bugged - Base Damage Ramping Way Too High

Zeffo Guardians base damage is ramping from 2k to 50k on tier 11. Unsure what causes the issue as most people do not experience it and can clear tier 11 on auto with no issues with Rotta level 110 (reporting around 5-20k damage at most near the end of battle). However for some people the BASE damage is upwards of 50k at the end (shown by basic attacks doing that much).

This is NOT an issue with the armor plating mechanic. There is some kind of scaling which is way off only for some people. Stuck at high 90% area of tier 11, while others can clear with nearly full health and protection.
