I'm thinking of respeccing my mages for fire tonight for some AV fun.

I figure spamming will be my main attacks

/cast scorch
/cast pyroblast!
/cast fire blast

I was thinking of speccing into improved flamestrike

I would also be liberal with applying Living bomb x 5 on three targets

Has anyone played this before? Got any advice?

My survivability as arcane last night was pretty good - I think the mod to highlight healers really takes the heat off the dps
