base it around the month long campaign, when it ends and restarts.
when you enter pvp at that time on any character you need to select EP, AD, or DC you are then restricted to playing that faction on your account for the duration of the campaign / month. once its up you make a new selection again and so on.
and no paying to switch mid way -_-
no this will not prevent spying or what have you because people will always have multiple accounts or what not. but it should prevent a large amount of casual *** baggery from taking place. as well as possibly reinforce the point of the alliance war instead of people swapping to whatever faction is winning half way through.
ESO player since beta.
game got too disappointing.
