Thanks, I didn't know about MP5 being suspended in combat. (Are you absolutely sure about his? I know mana regen is suspended in combat but I thought MP5 was a different mechanic... as you may have guessed, I've only ever played one caster class).

Still, the tirnket is an upgrade over the Eye due to the spell power alone. The Misguided Quill is useless to me, I'm drenched in hit rating and even when I throw away my belt to get the badge one I will be at 390 hit which is a good deal more than I need. Guess I'm back to hoping my luck will turn.

MP5 is not suspended in combat. Ask any healing paladin, they do not have any "x% of your mana regeneration continues in fight"-talent and Blessing of Wisdom (which is MP5) still gives them mana. The mana regeneration mechanics are explained in the Elitist Jerks TTT: Five Second Rule

Mp5 works regardless of combat status, however the dps value of mp5 is negligible. There would be no reason to put mp5 on healer gear if it didn't, also. (Note: spirit regen is not tied to combat, its tied to whether you cast a spell in the previous 5s, once you stop casting, even if in combat, it works.)

All three of the trinkets you listed would probably be better - I would go Scale/Ice crystal.

I'll just jump in here and confirm that [Phylactery of the Nameless Lich] procs off hellfire, drain soul as well as any other normal dot. This essentially means that I no longer can stack my [Muradin's Spyglass] pre-fight though, but pulling all cooldowns the first 10 seconds of the fight and I end up with a fulls tack of muradin's almost instantly as well as a procced Phylactery, and if I'm lucky, also a t10-proc, lightweave and ring proc. The spellpower this provides the raid as a demonology warlock is insane.. I have been getting reports of my Demonic Pact almost reaching 700 sp!

You can stack Muradin's with rain of fire and hell fire pre-fight.

Unless they fixed that recently.

I have never been able to stack Muradin's with rain of fire, only hellfire. And because of phylactery, hellfire is no longer an option.

Yeah, sure that would be very nice if I would know exactly 85 seconds before pull, but I really don't consider that a realistic option though. Muradin's ramp up time and the fact that phylactery only procs by periodic ticks still lets me get a few stacks though. Of course, re-equipping is the optimal solution, but I can't imagine it working out for the better of the raid very often.

Muridan's spyglass stacks on damage not on spell cast. This is nice, in that if you SoC hits 6 mobs you get 6 stacks immediately. As HF and LT don't cause damage in the normal sense it won't trigger. So if you switched from IotDS to Muridan's thats why you can't use HF/LT. Both those still work with IotDS.

With Affliction you should base your trinkets depending on the fight. NMIC impressive numbers is based on stationary fighting with 100% time on boss and a "phase" change to sub 35% hp after 3 minutes. The further you move away from that type of fight the more attractive other trinkets look. For example, Blood princes. You have to change targets every 45 seconds NMIC is rather lackluster in this fight (Gunship also). But even on a fight like saurfang or putricide add priority is such that you may be away from the boss for more than the 8 second window a hasted corruption allows.

This is not true. I pre-stack using rank 1 Hellfire.

I think he's referring to health funnel.
