There's something vaguely ironic about this thread in which many of the greatest WIS champions are discussing the pros and cons of Champs Leagues, which are fast becoming moribund. A great intellectual exercise, but it's fast becoming a moot point, isn't it? Sort of like discussing whether the dinosaurs had healthy eating habits...
This is intended as an observation, not a criticism. Guess the consensus is that a combination of fewer WIS players, a tight economy and the ubiquity of the fatigue strategy killed the Champs League concept. Hope WIS comes up with a replacement, and I guess for now most WIS champions focus mainly on competing in theme leagues and progressives.
