Experiment with Swiss deployment. Pike need not be in four columns of two elements each. Weigh the advantage of echelon deployment versus line abreast.
I started running my Swiss in an echelon formation ever since David Kuijt ('memba him?) showed it to me. I don't know if it actually helps them, but it looks really cool and I've had opponents tell me it messes with their minds. Psychological warfare! --So, it's at least of some value.
Yes, I had a similar reaction, “why did you do that?”
