PoE TripMcNeelE builds

According to PoB my DPS is combined 1.3 million. Im copying the MaxRoll LA league starter guide. My build is literally just a copy. According to their PoB, they have 16 million DPS. I know Im shy a couple levels and one gem. My bow DPS is good. Where am I missing 14 million damage?

Lightning arrow is really fun but from what Im seeing tornado shot is better? Is that true? If so, what specifically should I do to make the switch. Idk if I'm doing something wrong or have bad luck but I only have 3 divine - not a lot to work with.
