Mine also hit a little harder, because I have about 5% more Mastery and about 4k more attack power.
I did, however have 25 Lava Lashes versus your 21, with the shorter fight time. I know Lava Lash isn't at the top of the priority, maybe you were just unlucky and it was coming off cooldown at the same time as other, higher priority abilities (or perhaps Fire Novaing the shield adds ahead of it?), but Lava Lash was definately lacking.
Lightning Bolts were very similar, mine hit harder because of gear.
Tl;dr, I think you're just a little undergeared.
