The word has finally come down regarding character slots! While this should make most players happy, there will be some casualties in the form of the players that were waiting for this announcement to re-sub. They still have a benefit, just not as much of one.
Froobs will have the 8 slots players have always had.
Players with a subscription AFTER the 18.6.2 patch (including re-subs) get 10.
ACTIVE subscribers when the 18.6.2 patch hits get 12.

Note: The wording was changed to reflect the "point of no return" being the upcoming patch, instead of the merge.
