Hey,
I think Lyksus missed the fact you used the Eldar MMS rules.
Official rules:
MSM = Move Shoot Move
Eldar MMS, unofficial:
MMS = Move Move Shoot
Thus no more movement in the ordnance phase with this, but a double move in the movement phase.
Eldar MMS is adapted by the fanmade BFG:R(evised) rules as well.
The Eldar MMS rules have a long history and have been created to make Eldar more balanced & logical.
