Nothing is planned more than the general idea :
Scenario 1 :
Imagine you play order. You connect your character and you are locked for XX hours. During this period, IF the opposite faction is outnumbered, you'll be able to join and "break" this timer. Connecting on Destro will "lock" you for XX hour on Destro (unless order be outnumbered and then ... you keep the idea i guess ).
Scenario 2 :
You play order. You connect your character and you are locked for XX hours. During this period, if your faction is outnumbered you will stay on order faction. In the end of these XX hours, you'll be able to move on destro faction (and then being locked for XX hours ).
Scenario 3 :
You play order. You connect your character and you are locked for XX hours. You play XX+1 hours on your faction. You wont have any lock and you will be able to move on opposite faction whenever you want (and then you'll be locked for XX hours again)
On side note : No idea about changing tiers to play. But i guess this lock will impact T2+ and probably not T1. Dunno if there are simple ytechnical solutions about it.
Seems fair isn't it?
