country or regional preference in clan war match

it will become more interesting if war matching is done on country or regional preference. priority is given to regional clans of same caliber and if not found or available then it went to global search.

it will get more interesting to have a war with people of same country or nearby areas. same language and all. u can selected a preference country or region. if none available then server autosearch global to find a match anyway.

i guessed on basis that top clan or player shows both global and regional options. so it can b done.
