pretty good stuff, i differ in opinion on a few things but it's just a matter of personal taste.
~gloom owns when 6 slotted, hands down. moonbeam i hardly ever use other than to pulla mob or two out of a large group, 6 slotted it does only a little more damage than gloom and takes alot more time and end. i kill even con minions with enervating field on them with one shot of gloom and one shot of dark blast (both 6 slotted with 1 acc, and 5 dmg) again, it's a matter of personal taste.
~dark pit and choking cloud are much better than you think, it all depends on how you use them....mob's don't always stay in tight little groups like people want them to, and occasionally you will see crossfires in door missions and taskforces if you are pushing thru them fast....you wanna talk about not having to use heal very much, these two powers are your ticket to just that.
they give you the versatility of being that ghetto controller.....that isn't ghetto AT ALL....if you slot heavily with at least one or two end reduction in all of your toggles, there is nothing you can't do for your group. cone root, accuracy debuff toggle, damage redux toggle, slow/snare, AE choke hold and AE hold, AE disorient.....need i say more about the power and versatility?
~nightfall- i wasn't real happy with nightfall period, mebbe it's just cause im spoiled by thinking all of the other powers are good /shrug.....
again it's all a matter of personal taste, the only things i didn't agree with on the original post is that i personally love choking cloud and dark pit, and use them on a regular basis when grouping (not much when soloing). and i love gloom and use it ALL of the time, when grouping or soloing....it's also my favorite offensive power animation, the skull chasing a badguy running away still makes me grin evilly every time i see it....and i love the thought of sending a glowing eyed evil skull towards an opponent when and if pvp ever comes out
things mentioned above i would definately reiterate on....
~mutation being optional, if you need to res...you messed up, there is no benefit to ressing in this game other than to save someone the run back really, i have never bothered to get res....tho i will at 38 just to have for the higher lvl missions and taskforces etc, pre 35 i have never once needed it.
~lifedrain is worthless, i had really hoped it would be alot more damage and or heal than it is...especially seeing as noone can even pick it until 35, unless it gets t weaked in the future it is utterly worthless unenhanced, and as unhappy with it as i am i don't see myself slotting it heavily just yet..perhaps in time. i also felt myself wishing lifedrain had alot better graphic to it, sort of a cross between the dark powers look and the kinetics debuff animation.....would be a neat power if it looked like you were just snatching the life and soul right out of a bad guy :P
i've tried and played almost every power set to at least 10 or 12 now, and i have to say radiation/ dark is the most fun and versatile combo i have messed around with yet, and is definately my favorite character. much <3 for this build, thanks devs.
