Let's talk trade (and no, not trade like a market so you can bug me about GHorns and Hawkmoons). Let's talk about Guardian to Guardian trade within the battle environment. Situation: 4 Guardians of any type are running a Nightfall Strike. Question: How can Bungie create value incentives to keep users interested in playing once loot incentives diminish? Easy. First, what is one of the most valuable assets a Guardian has at their disposal during a Nightfall Strike? Super Energy. This asset possess high value because it is scarce within the battle environment. This scarcity is a fundamental aspect of Bungie's ability to create teamwork and strategy value for end-users. In order to create more incentive to play the game, we can use trade to push the production possibility outward, thus creating more value, strategy, and teamwork within Destiny's battle environment. What if Guardians could trade Super Energy? What if specific trades between Guardian types could allow for higher damage output at the expense of consuming two super energy meters? For example, a Titan (Defender) and Warlock (Voidwalker) both have full super energy meters. The Nexus has only a fraction of health remaining and a spawn of Vex have caused an unsustainable amount of damage output for the Guardians to survive because they are low on ammo, health is dwindling, and the two other players are downed in positions where they cannot revive. Currently, the Voidwalker would use nova bomb to wipe out one flank of enemies and the Defender would cast a bubble shield to protect the other enemy flank. Problem, the user has gotten bored with strikes because nothing to this strategy has changed! Not to mention, they both died because they got swamped in a bubble shield. I propose, that when both guardians are within a set range of each other, they press left button, right button, left stick, and right stick simultaneously; they can combine their individual supers into a massive cooperative super attack. It would be pretty fun if a Voidwalker and Defender could create a "Void Turret Gun" where the Titan shields the Warlock as it unloads a series of smaller Nova payloads that can be fired in any direction around the map. Given the dire circumstances, maybe spending two supers for one is the difference between reviving downed guardians and restarting the Nightfall for the third time. Got any ideas that would compliment this? Let's see if you can top my "Nova Turret" idea!
