For me, I used to think they were selfish pricks. Lately though, with the discovery of the Nightstalker, I feel Hunters and Warlocks can get along much better. Titans can pop a bubble, providing a safe haven for his friends as well as offering an overshield or damage boost with Ward of Dawn. While the team takes cover in this bubble, a Sunsinger could offer reduced ability cooldowns with Song Of Light. A Nightstalker could choose the right moment and tether a group of enemies, tether a large boss, or even offer invisibility. If done in a raid where the team has 6 Guardians, there could be 2 Nightstalkers, 1 Defender, 1 Sunsinger, 1 Voidwalker or Stormcaller, and 1 Sunbreaker. Altogether, this unit would annihilate any opposing force.
