Fish, I agree with the statement you gave, but, from what I understand (without quoting any specific reference):
a critical engine is one that most
adversely affect performance if rendered inoperative.
During a normal takeoff, with two or four engines, a turbojet aircraft would still need to use right rudder to maintain centerline (to counteract the weathervane effect of a left crosswind)
I may be mistaken, but would like to know the correct answer if anyone else wants to chime in
