[1.2.326] (4) Really last chance!

I thought he meant the damage reduction per mob.

You still need confirmation that damage over time is affected by Elemental Amplification or Elemental Wands, don't you? All I know right now is that it works off of your range; i.e. literally 160%/s. The 160% may be affected by Amplification or Wand, but your range surely is not, as those things affect spell base damage.
That's why I included the 3 different versions over there, for one elemental weakness was showed to affect DoT so it's not such a shot in the dark.
Also, wait until someone comes showing that FD and Paralyze DoT stack and then we'll see a F/P bandwaggon =D

Also, you shouldn't be including Magic Mastery's bonus into the equation. You don't include Bow Expertise into a Bow Master's DPS, do you? It affects their overall Magic Attack, which has nothing to do with %/s.
Well, bow expertise is a fixed bonus to attack while magic mastery is multiplying everything so you might as well include it in order to compare Mages to Evans.

Also, illusion is apparently 400% in the [KOR] Revamp thread, i'm no evan expert though.
