Newb General Mage Questions!

I am sorry ahead of time for the wall of text and prolly dumb questions!


Ok Originally my main was a Shaman so I really only been raiding on the mage for this being the second week. I have been arcane but since duel specced for Fire for specific fights. Last night we did H Maloriak and I played with fire a couple times and my damamge was really really low! I hovered around 14-16K when I was arcane I hoeverd around 19-20K. It was 25 man so needless to say the 2 other fire mages did about 23-25 every attept and the other arcane mage was around the same area as me. I know that is a fire fight I know. What is the propper rotation on that trash? I kept Blast wave on cd starting with a Living Bomb then scorched the target and hard casted a pyro then combustion. My first mistake was not watching ignite and I will fix that today by getting combustion helper but what else can I do? I mean it cant be a gear thing can it? I am sitting at 300 haste as arcane so my fireballs when I go fire are slow as dirt and my crit is also low but my mastwery is pretty good. Should I even out my arcane spec more? Mix some more haste and crit instead pure stacking mastery on the reforges? Also on reg rotaion on bosses I would start with lb, scorch and fireball till I proc a pyro and keep uplb and scorth right? I also noticed I was killing living by casting them to early I know 40+% damage from lb comes from the blast.
I really just need help with fire spec for the couple fights I need to switch back to fire for. Thanks again in advance!


PS- If you see anything in my spec gypls or anything just tell me I am taking all critisizm.
I was fire pre-patch, now Im arcane. When our guild started Cho'gall, I respecced fire but I didnt want to reforge/regem/regear all my mastery back into haste/crit. Thank god I tried it out in a ZA before the raid. I had horrible horrible DPS.

I was surprised, but I guess thats what happens when a fire mage stacks the be'jesus out of their worst stat.

So unless you're regearing after the spec switch, expect mediocrity.
