First of all, the server limit of 200 and over 100 systems, we are never going to see mass traffic all over. I hope to god Canon gets that multi server thing to work so eventually they can give each house its own server.
Secondly, never under estimate the power of "lolwuts" they will be there, they will lolwut and there will be more griping on forums.
...On a sidenote, I would like to suggest more limited trading between older houses and the Gallia as well with Gallic factions picking sides on houses.
So for example Council may start limited trade with Liberty ( I think they already do) and Bretonia while the Royals chose Rhineland (may be since they both are strict military and rhinelanders may be willing to assist GRN against a liberty Ally).Reason? can you imaging a GRN convoy going to New Berlin to get diamonds (may be essential in production of their oil burning ships) through Liberty (diamonds from Rhineland eh? both good and bad) and Bretonia (GRN... drop your cargo scum...from both Good and bad again) where they would be Shot on sight. This would make for epic cargo runs (with good rewards I hope, as long as the gallic ships are all red with Kusari houses).
