I read the update notes on this feature and the first possible outcome that came to mind with the data provided was that people would immediately pick Aldo or Maat Concord because most of their characters/bazaars are already in Lower Jeuno, then pressure their LSes to do the same in order to maximize that Concord's points. One month later the scoreboard would look something like:

1. Aldo 99999pt
2. Maat 10000pt
3. Pleuje 100pt
4. Flaviria 50pt
5. Naja Salaheem 10pt
6. Ayame 1pt
6. Apururu 1pt
6. Jacoh Wacondalo 1pt
9. Invincible Shield 0pt
So I showed up here to post. Turns out I wasn't the only one. To summarize with the few posts in this thread only thus far:

My take of it atm is essentially VW v2 that comes packaged with 1 of 9 additional server wide chat channels, with the best one receiving better loot, causing everyone to flock to it. Gear strength is up in the air as always. I hope by now you've learned that content lives and breaths on the gear you add to it.

Its a fun idea for a system, I like the sound of it but I have concerns about everybody joining the team with the most points.

Some reading here may not be aware of this, but I've been playing since NA PS2 release and I know for certain that this scenario has happened once before, at XI's population height: where most servers were 90% San d'Orian citizens and Bastok consistently came dead last in Conquest because non-Sandy nations were determined to be "marginally less convenient" and everyone went to the nation their friends went to regardless of personal opinion.

Matsui-tachi, I sure hope you have some way of preventing this from happening again--because if you don't you're likely to be spending multiple months trying to correct the situation or abandoning the system altogether. Please say you have a way.

(P.S.: I should also remind you that this same player behavior is what's currently resulting in people /yelling for only seven jobs in all Adoulin 119+ content--but that's beyond the scope of this post.)
