AND,.. they have only revealed 2 perks off each,.. in the twitch they wanted to give guardians more options for customization, there was multiple perk setson the armour shown,.. so basically one piece of armour could potentially have several different applications,.. like when we are forced to go farming,.. do i really need to replenish health from an orb? no,.. but primary ammo turning to glimmer would be handier,.. even though it is a Dumb perk,.. lol who knows? maybe a third perk on that Titan helm grants Airbourne,.. ;)
