Are you missing something? Seeing the strategy on a field is part of the fun of watching the game. Otherwise it would just be a push and shove game - and you can look to canadian hockey for that.
Of course strategy is important rugby. It comes at several levels. Basic ones, like do we play a power game or a running game, to the complex, preplanned dummies and running lines which come off of a set-piece lineout or scrum. The issue is that -- unless you are familiar with the game -- the patterns and strategies used by a rugby side can be difficult to spot. But that is equally true of any other sport.
