To me there is plenty of Overtaking in WEC. I'd argue the quality of overtaking is better because it is created organically, and not because one car has DRS engaged, or one car has already used it's KERS boost for the lap. It comes from hitting lapped traffic, one car being a little faster on the straight, then the other car being a bit better into the corner, or because it is a Diesel having a lot more low end torque on corner exit.
I know some people hate this aspect of racing, but I love a good battle of pit strategy and execution. Watching the splits rise and fall as two cars exchange pit stops is fascinating to watch. The 24 hours of Le Mans can and has been decided by if all the other cars can run 4 fuel stints on a set of tires, but you can run a 5th stint once or twice in the course of a race.
