Cl > LB. (In this case manaproblems are non existent)
1. Hits singletarget harder than Lb.
2. Hits 2 (3) more targets.
3. Lands the moment the cast finishes, so its less likely that the mob is dead.

Chain Lightning doesn't hit harder then Lightning Bolt on a single target. It's used because it has a higher DPCT.

If there is more then one target, then yes, it hits harder.

That was my point sorry if it wasn't clear enough.

DPCT? Damage per ?

Damage Per Cast Time

Thanks for this
