NA has no skilled players and EU is full of autoblockers. AUS wins by default.
If you must, just duke it out on strat for epeen.
Default? DEFAULT?
Nah, as Aus has a much smaller playerbase it is in the post-Warband phase where no one takes the game seriously any more.
Australia however a couple months ago was much better, but really just consisted of everyone just attempting to copy Keen tactics and fighting styles. This isn't necessarily a bad thing, as I've never seen any video of any foreign duel that even approached the quality of a Toad v Thorn fight.
So it is more along the lines of Australia losing by having no one play anymore, but you shouldn't be so quick to dismiss the playerbase.
