We had a really good few games last night on Gundam
The first video shows how bad the lag is with 2v2 when one player out of the four is playing outside your international region. Three players were in the UK/EU and one was in the US:

Second video shows how well everything works in 2v2 when everyone is in the same international region (All in the UK/EU in this case):

If nothing can be done to improve the infrastructure, can we suggest players who are looking for 2v2 games meet up in rooms that are related to their international region to help with lag? 1v1 players can use any room. The currently blank splash screen could be used to notify players of this.
