^this. It's not like they switched to LoL or something. Alot of strategies are viable in both games, and you actually come up with new ones aswell. Think about the asian teams and DYA; entirely different meta & hero picks, suddenly a wild defiler, forsaken archer and Sand wraith appear despite being rarely (if ever) picked in eu/na games. Also, while scrimming against Clan Milk I doubt you'll run at as intense drafts as you do when drafting against masterminds like Artstyle and Puppey, not to mention how greatly one's individual skills improve when constantly playing against better players in general.
