good working strategy is to have one player work on ads (especially blights) while two handle boss swords. ideally, have titan drop bubble (with armour or weapons) on boss platform, and hunter tether boss; two people on boss pull out swords (preferably exotics) and destroy boss, while dipping in and out of bubble to maximize damage/duration. Don't bother reviving the two focusing on the boss when they are inevitably killed as they will be doing enough DPS to boss to compensate for downtime. once boss is down focus on the rest of the ads.
