Needs to be looked at. This can be abused way too much, especially with Titans. Pretty much unlimited barricades. But if its looked at and played around with sure. Could be nice.

[quote]Hunter- cloak of the avenger -every time an ally dies, you gain a permanent 10% weapon and ability damage buff that stacks up to 50%. Lasts until you die (for pvp 5% buff up to max of 15%) Appearance- it would be a patchwork of other hunter cloaks, titan marks, and warlock robes. Warlock- bond of synergetics - you gain a 10% buff towards ability/ super damage and regen speed for each ally using the same element sub class. Stacks up to 30% (5% for pvp max is 15%) Appearance- it would be a bond with a swirling orb of energy that alternates between each element Titan- mark of th e protector -reduces barricade cooldown by 10 seconds and for each ally that dies you gain a permanent 10% damage reduction that stacks to 50% until you die. (Pvp you gain 5% damage reduction up to 15%, barricade cooldown bonus remains the same) Appearance- all 3 class banners sown together.[/quote] Anything that relies on allies dying is not great. Also, reducing baricade cooldown by 10 seconds would mean you would have a 20 second barricade every 4 seconds.
