Guild Wars 2

The WvW was added as opposed to separate players into Factions but the end result isn’t too different: your server fights against other 2 servers.
Choosing a faction gave you a goal to fight for that faction. Now as you can transfer servers every 7 days, it is your server versus 2 random servers in your region
So, if you had a non-winning week you will be faced with other 2 non -winning servers
In the end, every week you will have a fight that is not so important for you.
As we see now, people are transferring to winning servers so there is no difference if they transfer to a different faction.
Besides, we have in the game 3 factions already in PvE : vigil, priory and whispers. They should have made the WvW between Factions and not servers
Fighting for your faction will be more interesting then fighting for your server in my opinion.
Factions in WvW should be different once because vigils fighting priory and whispers will not fit the games lore, but different ones will because WvW will be a complete different game.
Choosing a faction should be a sort of questionnaire that will determine what faction you will start with,
Changing Factions will be a paid option as server transfer is now.
Restrict characters in the account to belong to one single faction.
