Not only are you replying to a 3-week old post, but I already answered it, in the very next post.
I have searched around but I didn't find anything about this: why do we cast lightning bolt with MW5 instead of chain lightning when available? the tooltip says that it does at least 200 more base damage.
Base on the EJ enhance shaman guide, it is because lightning bolt scales better in a raid enviroment due to the higher coefficient. To quote verbatim, "Chain Lightning will produce more base damage than Lightning Bolt, but Lightning Bolt has a higher coefficient than CL. This means that LB will scale rapidly compared to CL and in a single target environment LB will produce superior DPS."
Hope this helps!
