Thank you all for the input.
I have readed some where also the 3x destruction locks is also pretty good.
Specially with the talent points in pyroclasm combined with hellfire to stun aoe your targets down.
Only down side i see is that when you cast hellfire you lose x amount hp that is needed to heal back up.
And can put you when your to low in a vulnerable position.

@fuzzyboy I'm for 90%sure I will go with the first option (warr,3mage,pala) the mages I will make fire I want them to do as much as possible dmg unless there to many dungeons where there bosses that are fire immune
