Also even if the end result was going to be an engine shutdown, losing one of four engines is not an overly dramatic occurrence.
I daresay QF32 shows otherwise.
You can't make a blanket determination...every engine failure is different..and requires different assessments and different solutions.
You could have a single engine failure on a B52 cause significant damage. It's not in relation to the number of engines on board...engine computers aren't that smart.
