Some pointers for my new team? :-)

[Decadence]

SHAMAN:

/assist Focus
/castsequence reset=target Flame Shock, Lava Burst, Lightning Bolt,
Lightning Bolt, Lightning Bolt, Lightning Bolt, Lava Burst, Lightning Bolt,
Lightning Bolt, Lightning Bolt, Lightning Bolt

/castsequence reset=5 Water Shield, Flametongue Weapon

I understand that casting Flametongue Weapon every time you do water shield would keep it up guaranteed, but wouldn't it be a waste of mana? Does anyone else do it this way?
