It has been decided that the European clans are now free to battle American and European clans on ladder. EU vs. EU battle will work like normal battles. I know EU does best-of-7, however, for points scoring purposes, we do best-of-5 matches. I'm sure this can be worked out.
For EU vs. US battles, 2 maps will be done in one server, then 2 maps in another one across the sea. If it is tied 2-2, 1 map will be played in each server until one clan wins in both in a row.
