Every year people think that the list that won Worlds is amazing or almost unbeatable, but winning worlds has more to do with the winning player and the opponents than the list itself.
Sure, you want a good list, but you can't say that "Dengaroo won Worlds" unless you also want to say "Dengaroo lost Worlds."
There were multiple players running a Dengaroo list at Worlds ... and all but one of them got knocked out by other players with other lists before the championship match.
This is a good point. How many Dengaroo lists played at Worlds, how many losses did they suffer, and what lists caused those losses.
One Dengaroo defied the odds to take the title, the rest fell by the wayside, just like everyone else.
