The thing about warlocks, when in super they are very squishy, and they need to be in almost shotgun range to use the power. This means that unless you round a corner and surprise people you're not going to make it to the enemy while running down a hall. The warlock can easily be shot down with any weapon before they get to you. You have to choose between the power having range or chaining. You also have to choose between landfall and doubling the chain. I prefer to run extra chain, some prefer to run landfall. The power lasts as long as radiance does, difference is you can choose to have the extended duration, but this only happens if you have your grenade and melee full when you cast it. Out of all the new classes the warlock class is the most balanced. Titans need either the heal on kill or the damage reduction/health bonus removed. One or the other would put it in balance with the others. Hunters are fine, they are just broken right now. Once the bug is fixed all will be right with the world.
