The only sense of raiding community that existed before was the sense of superiority that data centers had in their strats vs those of others. I still remember the initial hump of aether and crystal people disliking each other's strats and saying the others' was bad. Discords have now merged, and NA is now the community.

As for finding DSR parties in my own data center, at best it would have been 1/3 of the people interested in ultimates. The ultimate community is already small, so merging them all has been the best thing that's happened.
