Spell penetration...good or bad for FFB mage?

thankyou, is there anyway to get around the partial resists?

With the current Buff to Imp via ruin i started modelling an alternative "Strong Imp" spec in Simcraft using the warlockt90_13_58 profile, ofcourse using 3.3 in the SIMC options menu.

The World of Warcraft Armory

Simcraft calculates total DPS with the "Strong Imp Spec" at 10866
Using the default Simcraft 0_13_58 profile Dps is calculated at 10738

Furthermore if i swap a point out of backlash into UnholyPower simcraft calculates dps to 10899

Am i doing something incorrect here?

It may be worthwhile dropping SL/ISL for a stronger imp from what it seems like so far.

Anyone with good/funny stories in which GDKP doubters receive their comeuppance? I was lucky in not having anyone mock my initial GDKP-run announcement on the server forum, and in only having one or two minor cases of Trade-channel morons mocking the idea in chat, but that's of course not the case for many other pioneers. Having done a lot of reading of GDKP-related posts on the Blizzard forums before and after conducting my first one, I have repeatedly seen the following pattern:

A. "What do you think about GDKP? This Elitistjerks thread says . . ."
B. "The raid leader will steal the gold! It's wrong to sell loot! It'll encourage gold buying!"
C. "Baddies will get loot! Only rich players will be able to join! This server is too backward for it to work!"
D. "I don't know, but I'll try it."
E. "Me too."
A. "GDKP run at ________ at ____ pm."
D. "Wow! We killed Anub and I made a profit despite buying an item! Sign me up for next week!"
E. "I went broke buying that trinket, but it was worth it. Sign me up for next week!"
F. "Nothing good for me dropped, but everyone stayed despite wiping on Anub twice. Sign me up for next week!"
G. "My guildmates told me about GDKP. Sign me up for next week!"
H. "I'll bring twice as much gold as the last time. Sign me up for next week!"

Etc., etc. The funny thing is that C. and D., like roaches that flee once the kitchen light turns on, never reappear once a single successful GDKP run occurs; I think I saw exactly one thread in which skeptics acknowledged that their concerns had been misplaced. Would that we had more honesty and forthrightness everywhere in life, not just in Azeroth!

(That said, we should also hear about cases in which the skeptics are for whatever reason proven right so the rest of us can avoid those situations, whether on our first or fifteenth GDKP run.)
