Weird Shaman Auto Attack numbers

[RogueUnseen]

Not a huge concern but something that caught my attention. Shaman auto attack damage is lower than expected for a melee class...

Auto Attack damage totals on Goloch:
Paragon 130k
Riftblade 140k
Pyro 110k & 68k
Marksman 111k
Sin 165k & 155k
Shaman 82k
Archon 84k
Harb 141k

It's not a disconnect issue as only a single Ekkehard's Grasp went off for the duration of the fight. Again, not a huge concern but to have less damage in auto attack than a Pyro and an Archon and over 50% behind other melee classes, something seems off.

Was the shaman using 1H + OH while the other were using 2H ?

2H- Hammer of Three Fates
