Koalanoob dominanting NA?

Does that mean EU always was competitive and Americas was always shitty compared to?

in a sense, yes.

The only reason koalanoob didn't do well in EMEA is because Navi doesn't think of duelist as a role, to them they are just information drones that lead hiro and ruxic in to clean up. He would have most likely been much better on most other teams that actually knew how to use him.
