I've been away from my mage for a bit, but I am looking to start raiding on him agian. I'm about 5 badges short of 155 badges to get chest/shoulders for 2pc. As with all gear changes, this means more stat juggling, which means hit juggling through talents and a respec.
Current set-up.
I'll list out the talents I'm looking at and my thoughts on each with the information I could find in this thread.
Precision -- Opportunity cost for points in this talent are points in Frost Warding and Ice Shards. Currently my first place to grab hit.
Ice Shards -- Useful only for AoE unless mirror images benefit from this. Not very useful in boss fights, therefore low priority
Frost Warding -- I have this talent because I have Incanter's Absorption as well. How useful is this mana gain and survivability? Should Ice Shards be prioritized above this? How much value does this lose if you drop IA (see below)?
Arcane Focus -- Opportunity cost is a point in any Arcane Talent (focusing on the ones listed below)
Arcane Stability -- I remember reading that 60% was the golden number you wanted from this. Source/explanation needed.
Arcane Subtlety -- How important is threat reduction in today's raiding environment? Is this negligible because of Invisibility and Mirror Image for threat management?
Magic Attunement -- I grabbed a point in here for convenience and out of my BC mage upbringing. Is this really worth it considering the boss fights in ICC?
Prismatic Cloak -- 3 points here provides an instant threat drop and some nice survivability. 2 of these points could come from Arcane Subtlety, as the threat drop negates the usefulness of that talent. Is the third point worth it? It triggers the GCD anyway, so you'll still be waiting half a second after you fade to cast your next move. Combine this with a cancelaura macro in that half second (spammable as the invis buff doesn't show up until you fade) and you have a threat wipe for the cost of a GCD.
Incanter's Absorption -- From Ensidia's forums: "fire/frost ward absorbs about 4.5k with 3k spellpower, which would be 675 sp for 10 sec, every 30 sec on fights with fire/frost damage." Is this worth the points here? What if you have Frost Warding?
Slow -- 1 point for utility. How many fights is this applicable to? This seems to be dependent on raid comp and if your raid needs that slow.
Please correct me if I am wrong about anything I posted and provide any input you have.
