Unless the NA scene leave behind all the drama, they will never be able to compete with the EU scene. Cloud9 achieved to go to the finals of 2 tournaments , but they didn't win them , so it doesn't mean anything.
If you would ask me for the perfect NA team , i would say the following 5 names :
Shroud , n0thing and Skadoodle stay , sean gares and freakazoid go and let their places to Hiko , the best player NA imo , and Elige , the Liquid guy who imo opinion has a great talent , even tho very young.
Not that Freakazoid and Sean Gares are bad or anything , but they cant compete with the skill EU players have like olof or krimz or device or dupreeh etc etc.
Freaka may be skilled , but he is dumb , overpeeks too much and does stupid decisions which have costed them the rounds many times.
Sean Gares is a very good caller , but just not as skilled as the others.
So yes , EU > NA anytime of the day.
