That's complete and utter bollox. I have a level 28 warlock, a level 26 hunter and a level 25 titan on my account, and I prefer the warlock over the other two hands down. The sunsinger has tremendous offensive power with his dual grenades and melee attack. On top of that he can revive himself if need be. Weapon wise there is no difference. I have never run out of ammo with it.
