Ok so, since your guild is in a alliance with another guild, your suppost to be friendly right? Well some people dont, so we should make it so you cant attack a guild alliance member just to attack them. Now if they are on the bounty list yes, but off of the list no.
Not feeling this one AKK, sy. I think it needs to fall on the player to make their own choices. This is one area that really brings a lot of adversity to the game and promotes rivalries which promote activity.
When I see someone with a guild alliance on my battle list but they are not clan, I don't attack but do the courtesy of asking them to clan as our guilds are in alliance. If they don't clan, and I might ask more than once, I then assume they do not want to so are fair game for attack - their choice. They had the offer. I might even talk to their guild leader as all alliance guild leaders are always clan. Then if the person runs crying their leader knows I tried.
As a faction leader in ZS I accept all requests such as alliance and enemy, and I continue on playing my game as I normally would. If you're an ally, you're not going to die any less. I fight faction members, faction enemies, and faction allies. Just because you get your panties in a bunch over a few attacks doesn't mean everyone shouldn't be able to attack.
