The title asks the question. Which two classes complement each other the most? All subclasses can be considered. My vote is for Warlock/Hunter. It's ironic that, lore-wise, these two classes hate each other. Anyways, a Nighstalker tether combined with any Warlock super is utter devastation. Not only that, but they feed each other orbs, basically chaining together their own two supers. What are your thoughts? Explain.
Hunters hate warlocks Hunters hate titans Titans hate hunters Warlocks hate hunters So... Titan / Warlock
For dps is Titan/Hunter Bubble with weapons of light Tether with black hole Tons of damage
Sunbreaker and void walker is an offensive maelstrom. Defender and Nightstalker pretty good too.
The add controlling skills of a defender/Nightstalker with Light of the Pack..? Absolute destruction.
Titans= brute force Warlocks= very intelligent Together it would be complete destruction.
