38 DC Necro spells and you'll do just fine on Epics according to some of you.
Have you folks DONE Epics with an Arcane who uses Necro spells? As already mentioned, my PM has a standing unbuffed 38 Necro DC and without using the right combination of spells to lower the levels, stats and saves of the TRASH in Epic, I ain't instakilling anything in Epics unless it rolls a 1. Enervation, Solid Fog, Circle of Death, Symbol of Death, Curse..then, IF I'm lucky, I'll toss out a Wail and kill 2 of the 8 mobs trying to kill me, toss off a FoD and maybe pop another of the remaining 6, leaving 5 mobs that need to be dealt with while my CoD and WoB are on cooldown. And that all depends on me NOT getting hit hard enough to have my concentration broken, and guess what, Epic mobs hit that hard without trying. I just blew a lot of SP in the process and might have killed 2 to 3 mobs.
Hey, you totally worthless, useless and unwanted Melee, I THINK you might not be so worthless, useless and unwanted!
In the SAME time it takes me to cast the proper combination of spells and wait for cooldowns, 2 Melee have killed all 8 of the mobs.
Unlike the statements of Sirgog and Tirisha, this isn't a guess, this isn't a theory, this is first hand HARD data gathered in Epic quests. Is my PM a GOD in Epics..no, but he CAN instakill things now in Epics, with some luck and proper spell usage. 6 spells and I can't kill as many mobs as 2 decently geared Melee in Epics in the same time frame though.
Now, outside of Epics, short of a few Elite Amrath quests, my DC 38 is more then enough to ensure the death of anything not a boss. But this IS a dedicated Necro build with everything geared for just that purpose. My Air Savant, with her MASSIVE 32 Necro DCs..yeah..please, even in Shroud trash ignores her FoD and Wails half the time, I don't even bother with them in Epics, total waste of SP. My Savant employs the tried and true method of NUKE EM FROM ORBIT! Meaning she hides behind the totally useless and unwanted Melee, uses both Diplo and the HElf Diplo, pops some Solid Fogs and tosses the largest most powerful AoEs she has on trash, since her Enchant DCs are less then her Necro, along with Surge on occasion..but that is mainly used for bosses, even in Epics, since even in Epics, trash mobs just don't survive the Melee long enough to stack that Surge.
Ya'll are just funny with your talk of how you ONLY want Casters in your groups and how effective that is compared to wasting slots with a few Melee..and then telling us that a 38 DC is going to work in Epics. Go on, take 6 Casters who top out at 38 DCs into an Epic and let us know just how well that goes for ya. And I thought beating out mob deaths with player deaths in Undermine was fun...
And, about my PM with his 38 Necro DC. He's not used a single Int tome, doesn't use ship buffs(stat/DC boost, LOVE the Resistance buffs!), nor does he use Yugo pots, and I never can seem to find a Spellsinger to run Epics with, just Warchanters. First lifer, just look at MyDDO, Fleshmelter is my PM. Add 4 Con, 2 Int/Wis/Chr for Lich form(always in that in quests) and remove that silly scepter he's holding atm

Couple of TRs as a Wiz and I could easily pop a 46-48 Necro DC. I am at heart a Powergamer and I do make some of my builds accordingly, I just don't bother to grind out that gear...sue me.
