Where Is The Logic Banning New Characters For Existing Accounts on Congested Server?

[EorzeaWanderer]

As other have said there is no ban. If you want to create a character on a specific world to play with friends, you may want to start checking early am (like 4-6 am where the majority of the player base of that world is located). Some worlds might still be congested at those hours but it is much better now than it was a month ago.

This actually won't work for world servers that are designated as "Congested" worlds. It is not possible to create characters on those worlds at any time, until SE actively removes the "Congested" designation.

Other worlds might temporarily step in and out of the "Creation of New Characters Unavailable" status, because that status is dynamically assigned and removed based on live login counts. In this case, the above advice (creating a character in off-peak hours) will work.

If a world is marked as "Congested", however, it is blocked from all new characters until SE decides to reverse the decision, which is usually re-evaluated and applied in the next patch.
