Deleted my Titan recently to get the stranger's rifle and some other guns again, so went into Iron Banner this time as a Defender Titan which I've never done before, it's actually a lot of fun! Armor of Light makes you almost indestructible when you're in the bubble, and your allies also, so you can use it to take a critical control point, or in this case, get that 10 kill streak bounty done! Perks were Bastion to make the bubble last longer, and Untouchable to reduce its cooldown.
