Will there be a fame requirement for the guild to take/challenge an outpost? (ie for an outpost in Zorai would need say 50 Zorai guild fame, 25 Kami fame) [Submitted by rushin (EN)]

No, there won't be any fame requirement on the Outposts. There was no need for it in the current version, and it made things more simple - the set of rules is already quite lengthy.

Are the "original" NPC owners of the outposts members of one of the current tribes? [Submitted by sprite (EN)]

No, tribes won't own the outposts at first, but some other NPCs you have already met will... If you want to know more on this subject, you'll have to follow the upcoming events.

If an outpost is occupied by a guild, is the area surrounding it PvP all the time or just during the attack and defense phases of a challenge? [Submitted by rushin (EN)]

Only during the attack/defense phases - and only for those who choose to participate to the conflict.

What ruleset will the PvP around outposts take? Same as PR GvG or something different? [Submitted by rushin (EN)]

If you want an analogy, it's somewhere between FvF and GvG rules.

What does it mean? When a conflict starts on an Outpost, everyone who enters the area surrounding the Outpost gets a pop-up asking him what he wants to do; there are three choices available: attacker (not available to members of the defensing guild), defender (not available to members of the attacking guild) and neutral.

Defensers can't attack other defenders, attackers can't heal defenders, and vice versa. The two guilds keep the option to kick anyone from their camp, at any moment.
