Was just thinking of an idea that I would like to share for Elemental shamans.
Remove the cooldown off chain lightning and make it single target, allow it to dip into all the talents that LB does so it scales around the same and now you have a Higher DPS but higher mana option to make your rotation and gearing more dynamic.
And to compensate for the loss of bouncing CL and lack of instant cast,
New spell -> Fork Lightning. Instant cast, hits 3 enemies for X dmg. 6 second CD.
