I am getting the following Spellpower coefficients, untalented and tested wearing only gear that has a flat increase to Spellpower, Intellect, Crit or haste. (No Set bonuses etc) The numbers are derived from Blizzard Tooltips and Paper doll stats at different amounts of gear
Frostbolt 0.8572 3.000/3.5
Fireball 1.1243 3.935/3.5
Scorch . . 0.5382 1.884/3.5
Frostfire bolt 0.9768 3.419/3.5
Arcane Blast 1.0573 3.700/3.5
Icelance 0.3774 1.321/3.5
The only one that makes any kind of sense to me is Frostbolt. Are Blizzard now fine tuning using SP coefficient?
As of last night, 18 Oct, Frost Specialisation only gave 15% damage increase, not 25% as stated in the Talent Summary.
