I think what Drew means is instead of "wasting" time (to say it in a politically incorrect manner) beating people he knows he will beat in the poule phases all day long, he'd rather have longer matches in the final phases that actually matter and determine the ultimate results.
I'm in favour of his proposition, if it doesn't need much more playing time overall. Just reduce the group stage a bit, which involves beating generic newbie A,B,C,D with 4-0, and extent the matches that determine who can actually call himself World Champion.

This can be achieved by splitting the qualification into 4 different groups for example.
I definitely think the CDM puts too much emphasis on the qualification stage and in comparison too little on the finals. Especially for an event that states that it produces "official" World Champions. This seems especially true in Battle Mode, where a first to 20 match can be reached quite easily and adapting to your opponent can take a few matches.
