Castsequence on LB for PvP?

Utilizing Thunderstorm is awesome, but it's hard to manage on round robin. So I had an idea for the initial start of the fight. (On an extra button, incase the situation needs more diversity, I don't want to rely on this macro alone.

Shaman 1:
/castsequence reset=45/combat Purge, Chain Lightning, Lightning Bolt, Fire Nova Totem, Lightning Bolt, Thunderstorm, Chain Lightning, Lightning Bolt, Lightning Bolt, Totem of Wrath, Lightning Bolt, Chain Lightning

Shaman 2:
/castsequence reset=45/combat Purge, Chain Lightning, Lightning Bolt, Fire Nova Totem, Lightning Bolt, Purge, Chain Lightning, Lightning Bolt, Lightning Bolt, Thunderstorm, Lightning Bolt, Chain Lightning

Shaman 3:
/castsequence reset=45/combat Purge, Chain Lightning, Lightning Bolt, Fire Nova Totem, Lightning Bolt, Bloodlust, Chain Lightning, Lightning Bolt, Lightning Bolt, Grounding Totem, Lightning Bolt, Chain Lightning

Shaman 4:
/castsequence reset=45/combat Purge, Chain Lightning, Lightning Bolt, Fire Nova Totem, Lightning Bolt, Purge, Chain Lightning, Lightning Bolt, Lightning Bolt, Grounding Totem, Lightning Bolt, Chain Lightning

I'll mess around with it tonight, the idea behind this is so you don't have to rely on casting at the same time, in order to make a toon do a skill while not already casting. So you get max out of the rotation for the first 20 or so seconds, utilizing aoe and thunderstorm without loosing lb/cl dps.

Think this would work, or maybe a waste of time? :/

I could seperate Purge, didn't realize about the nothing to purge thing.

I was just meaning rotating Thunderstorm into the macro's without loss of casting time on the other chars though.

I use:


/cast [modifier:shift] Purge
/cast Lightning Bolt


Purgex4 at beginning then just continue to LB away.
