I cannot tell whether we disagree or are posting at cross purposes.
I'd doubt there are many here who will be arguing for boring placements. The differennce, however between an excellent placement and a stupid one can be as little as 3 feet, I'd think.
Take a thereortical simple 2 tier green. Flat, slope, flat. On the slope, the ball placed on the green by hand will roll. It is therefore impossible to lag putt, from any direction to the slope. How close to the slope is acceptable? Too far away is, as you say, probably boring. Too close is impossible. Somehwere between the two is acceptable and from day to day more or less challenge can be offered. This basic logic can be applied to all varieties of greens, however subtle and I'm sure that if the greens themselves aren't rotten there will be plenty of variety to be found.
