If you don't select any faction, you will be neutral.
No problems found so far.
One suggestion of a player:
Would be nice if you were able to see, which faction a player is.
Maybe a little symbol or word somewere at the title can be useful.
Edit:
Some players are dissatisfied about the "neutral" situation.
Would be better, if neutral-players were not attackable by the other factions.
On this way players, who dind't want to take part on the event, are able to cross the area without any attack.
