You forgot about the time the hunter was in his final stand with hive surrounding him on all sides. The hunter thought about how he has failed the tower. This is it, the end for the hunter. BOOM a Nova Bomb crashes in and destroys all the hive. A warlock glides in and helps the hunter up. A Titan walks up to the two of them. Together they destroy a hive camp. Warlock forever. Titan forever. Hunter forever. I'm going to be a Warlock but all are great.
