I personally thing it would be amazing if you could declare war with another Clan/Alliance and be able to take them down in different spots around the planets while exploring. Imagine you and your fire team are out exploring in Old Russia, when suddenly you come under sniper fire. You immediately react, expecting the Fallen or the Hive to be attacking, when you realize a red name tag is spotted in the distance from where the shot came from. Its and Ambush. Your simple group exploration quickly turns into a gun fight for your life. You are pinned down in one of the caves that are supposed to have a hidden chest, but neither side will make the push against each other. You call for help. Once more of your clan mates rush in and hit them from behind, you and your remaining squad move in and waste the rest of your attackers. I Don't know about your guys, but I think i would REALLY enjoy encountering scenarios like this. [b]EDIT 8/10/14[/b] Perhaps I wasn't clear enough. I understand that there is the Crucible for PvP, but those maps hardly can reach the scale of what I had in mind. I agree, PvP in Exploration mode isn't a good idea, especially when its a good way to just kinda go on a free roam with no worries. I never said though, that players would be forced to worry about being attacked at random. It would only be if you and another clan had agreed to a clan war in the first place. Think of it as a Duel between clans to practice at strategic control over a large area as big as the world we explore in PvE. However, something like this (After further review in the comments) would most likely have to be in a separate zone all together. However, like in the exploration zone, you would be able to find hidden loot Caches with more PvP oriented weapons. Nothing crazily OP, but something that would give you a bit of an edge in the Crucible. Story wise, I know the Guardians are supposed to be united in the front against the on coming Darkness. However, I personally think this would be like an extension of the Crucibles influence in getting Fire teams more adepts to using their surroundings and mastering the Land around them to overcome any threat, While still in friendly competition with the Other Guardians. After all, Guardians are some of the strongest warriors in the Solar System. What better sparing partner to have in the battlefield than another Team of Guardians? I understand this would probably be a whole project for Bungie, but I think it would be a fun and bonding experience for anyone who wants to enjoy working with Clan members, along with Raids, Strikes, and Crucible PvP.
