Why not make 2 nwwc server one in France for west conference: NWWC-1 - fra,GB,germany,Netherlands,Ireland,belgium,italy,spain,austria. One in east europe (east germany can work)for east conference: NWWC-2. - Turk,ukrayn,russia,greece,czech,Poland,bulgaria,etc..
If one nation from east conférence face an other from east too = they play on NWWC 2 (then they got a large better ping).
Like this if there is west vs west = NWWC-1
if there is West vs East = NWWC-1 cus nwwc -1 is better than 2 if we take the average ping of both nation.
And this system allow fair fight against na and west/east eu:
NA vs west = NWWC 1 - New York (host by na captains)
NA vs east = NWWC 2 - New York.
