Hello I am posting because I need others to take note of the coeffcient problem with warlock spells. I imagine other classes are suffering from the same issues.
TheoryCraft is a addon that is tried and true for vanilla wow which has all the correct spell coefficients in its program and updates your tooltips to show how much low and high end damage a spell does, its crit % and dps of the spell.
Corruption and agony are not receiving 100% bonus from spell damage
Rank 6 corruption does 666 damage over 18 seconds. These ticks occur once every 3 seconds. The dot ticks for 111 every 3 seconds with no damage gear on.
With 100 spell damage gear on the spell is supposed to do 766 damage over 18 seconds with 127 damage per tick every 3 seconds. It is actually doing 122 per tick on nostalrius.
Shadowbolt is not receiving 85.69% bonus from damage gear.
Proof rank 9 Shadowbolt without spell gear or talents = 455-507
Adding 100 spell damage gear my shadowbolt should be doing 541-593 but my shadowbolts are hitting targets for 524-526 well under the minimum they should be doing. These are mobs without any defensive modes or resistances.
