You have a point. I just finished a private session today with my Eskrima coach who is of the same persuasion as you. He feels the initial contact should in one jolting move deflect, strike , turn your opponent off-line, and mess up his stance. Different system but same objective. By contrast my Ving Tsun, primarily derived from WT, is more like what I previously described. Both approaches can work. As to which works best, I believe it depends on the fighters and the situation. You believe differently. I'm OK with that.
Just as an aside.....this is also exactly what Robert Chu teaches in his Chu Sau Lei Wing Chun.
