Hmm i put it there by mistake  sorry i wanted to put it on iceblock.Ok i'll respec as soon as i can.

   Ok it's kinda boring to discuss it over and over this so..Polter how is your spec at etemmu? You didn't linked it to us.Pyro how about this build Creme anticelulita prefer some mana shield for more protection instead of counterspell.Anyway make ur comment plz

    M8 u cant make only build for bosses thats impossible.You must always put some talents somewhere to go on.In yours spec you have counterspell!that is not a waisted talent point?Or Arcane Focus Arcane impact?you will cast arcane explosion to the bosses or arcane blast?Because arcane blast is the spell that it's worthless on bosses and it burns your mana.Pyroblast u mean is for PvE?You will cast a 6 sec spell to a boss?Anyway I dont believe that any fire mage can survive at gruuls.Basically pyro u was frost at gruuls that time(full frost with elemental)and u was on the top 5 of dps.so i think if all mages was geared as you all the mages would be on top 10 at least.

Polter

That trinket u are using i think i should get it too .As for warlock that i was saying is that a warlock with blue/green geared can add more dmg that a same geared mage.Especially an afliction warlock can do more dmg than the mage in the long fights and i am mentioning these things about warlocks because pyro was disapointed about dps meter in gruuls lair last week.About the 13 "lost" points you cant put them anywhere else for spell dmg or something if someone want to spec frost,otherwise it helps in some thrash mobs at kara.
If i am wrong plz Make a build to see where u can put these talents to be more effective for the bosses as frost.

     I suppose we are all trying to do our best to get better items for our dmg,heroics such as crafted items and the bad thing is we are depending on drops and we must w8 for CDs and that means too much time...Anyway In gruul's lair last week the truth is that they were only 2 mages in the top 10 of dps.That was because the shadow priest,the rogues and the warlocks are better geared than the mages.(Warlocks btw dont need dmg.they have only 1 buff which giving to them +100 spell dmg.OMG nerf warlocks at last!!!:D)anyway about the talent builds...frost was always the best PvE spec because it is the most survival for mages.The truth is that he is survival but he luck at dps.To be frost and be good at dps you must have over than +950 dmg at least.I have currently +900 but i am working on it and i am talking about this build of frost : http://www.wowhead.com/?talent=Rf0VZZVVGcofxsiqx
     The new crafted items they have lot of dmg that's true but they luck a lot in stats.look at the boots of frostweave set.+9 intelect!omg thats nothing!or the spellfire gloves +10 intelect and no stamina...so if u will spec arcane with arcane power you will run out of mana if the 1st minute...The gruuls fight and even better in the High King Maulgar that fights keeping too much and u should conserve mana.These fights are taking 6-7 min at least and you will be out of mana at the 3 min cause they have a lot of HP and a crit about 4000 is 1,5%.So arcane is not a solution.Arcane was and will be only for PvP.You only need Arcane Subtlety,Magic absorption and Arcane Concentration from arcane.
     The new PvE spec imo is this http://www.wowhead.com/?talent=kf0EZtgG0fcc0eRt.It has dmg as a fire spec and conserve mana.If i had the spellfire set i would spec that way.Pyroblast and blastwave are not for PvE.Dragon's Breath can save u from the mobs at kara that you must do aoe.Disoriend is imba.
     I like to hear some comments.I hope the links to work.TY for reading this;)
