In short if you're in a town and the warning gump appears then the best thing to do is drop the trader quest and recall out because 30 seconds might not be enough time to leave on foot. Could we possibly get a little more warning time say a minute or 2 so we could at least leave without have to drop the quest?
If we don't make it out in time and go orange then why should we have to get killed to reset it? Wouldn't leaving the town suffice to reset back to blue? or at the least reset at server maintenance? Perma orange for having your play interrupted by a PvP battle is going overboard to protect the sanctity of the battle.
