While flagged up, players cannot enter the capital cities of the other factions, nor can they enter Caerleon.
While you’re flagged for a faction, your cape will change its emblem and colors to that faction's style, and you will be able to attack guild or alliance members who have joined different factions.
--> no enter of carleon...does that mean each town gets a realm gate?
-->" be able to attack guild or alliance members" .... seriously, you think someone attacks it's own guildleader, and full loots it??
And where is the solo and small guild part? i see another Zerg fest...
So far for me a bit dissapointing
You can de-flag anywhere, it will take some time though such that you can't easily use it to get away from a faction fight. However, you cannot flag for a faction everywhere - this can only be done in the faction cities.
Please consider add a loot protection in this patch.
While there are ZvZ faction fight there might be some blue flag running around waiting for someone to die and take some free loot without taking any risk.
