Ha! i know right.
However, coming from a player who switches between the Asia servers and Americas, there is an interesting trend which i had observed.
On the Asia servers (Korea, China, Taiwan, Hong Kong), the players typically go all DD with nary a healer and definitely not a tank. It is not uncommon to have both teams just trading shots with mirror Ashe (mandatory pick), Widow, Hanzo matches and no one pushing the payload or whatnot.
However, on the Americas servers (it would be the South-East Asia servers for me covering Singapore, Malaysia, Thailand, Philippines etc with the odd mix of East Asia and sometimes Australia), it is almost always 2-2-2 or at least 1-3-2.
Personally, i find this trend to be quite interesting.
