I notice you use alot of chain lightnings on single target bosses... Lightning bolt scales much better.. Your not using your maelstrom stacks immediately so u lose a lot of dps if you were using your maelstrom stacks right away you would be able to throw out alot more lightning bolts making chain lightning with it's cool down not worth it also. Just noticed you soemtimes sit at full maelstrom for quite a long time.. I see now your only using chain lightning so your waiting for it to be off cool down while having full stacks in the time u wait for that one chain you could have already launched 2 almost 2 lightning bolts lol..
