Every DPS spec except for Mages and Spriest all have the same paragon +x% to all damage done. However Mages and Spriest have +X% done to Arcane/Frost/Fire/Shadow based on their spec.
The problem is, that all specs except for Mages/Spriest whos paragons effects all damage can boost the damage from their Trinkets, Satyr neck enchant, potion of deadly grace, etc. But for mages/spriest unless that proc does the damage their spec does it doesn't scale at all, and at 20/20 that is a 14.5% boost.
For example, the new legendary trinket that all DPS can get does fire damage. So all specs except Arcane/Frost Mage and Spriest who has their paragons get the damage done by that trinket increased by x%.
Can Mages/Spriest get their paragons changed to all damage like all the other dps instead of it being tied to a certain school of magic.
