Higan has his mighty armor for defense, Slimy has its ninja skills. Thing is, though Slimy poses an immense threat to any biological life form due to its toxins and ability to regenerate off the meat of its enemy, that shtick doesn't work on Higan. It has no direct way to inflict real harm to the pilot or the mech, and one direct hit would blow its lean, mean, smelly and squishy body right the fuck apart, and an indirect hit could take off one of its arms or its tail, severely crippling its ability to avoid further damage. 

The Magna Pater's only saving grace, only advantage, only chance to have a chance, is by being the best damn dodger it can be. Even then, it's already lost half its face, three ribs, and the tip of its tail.

I'm not saying that Higan should be taking more damage, no. I'm just justifying the capacity of the Magna Pater's evasive skill in this battle.
