( I'm French, excuse me if there are any mistakes ).
i started playing my mage when 1.8 and the emerauld dragon's where released. I remember running Molten Core and i liked playing frost on ragnaros.
But since then i never played frost again in raid. and i do miss that. Blizzard is breaking there heads on how to improve pve frost damage without making frost mage insanely good in pvp.
I came up with a spell and a talent i wouldlike you to discuss and tell me what you think about it.
First, i'd do a spell named : Hypothermia ( or whatever it's called in english ). It wouldn't be otherised in arena's ( like the warlock's maledection ).
It would go on this base : Everytime you cast a frost spell on a target ( by frost i mean frb / cone of cold, not ice lance ), the target get's a debuff. At 30 stacks, the target is considered completly frozen, and you must now throw a fireball ( gained with brain freeze or wathever ) to shatter the target, causing a frost explosion of 37000-41000 damage ( and works as well as an aoe ). I don't think in battlegrounds this spell would have any effect.
Secondly, i would do a talent named "Frost statue". This talent would be based as the hunter talent "sniper training". When the mage doesn't move for 10 seconds, he starts getting frozen, and gets a buff wich increases damage done by the mage by 5%. If he does'nt move for 10 second's more, he gains another +10% damage ( for a total of +15% ). And if the mage doesn't move for 10 other seconds, he gains the "Frost statue" buff, +10% damage ( +25% all in all ), and every three seconds he gets a free 100% critical ice lance ).
I don't think this talent would be used in pvp. I know that with my mage i don't stay more thant 3-4 seconds without moving. and for the fights that requires a bit of moving, lets say that the buff lasts 5 seconds.
What do you think of these ?
