Need build help: DS/DM

I've been playing around in Mid's for a couple of days trying to stuff everything I want/need into a Demons/Dark Miasma build and just keep hitting a brick wall.

Could someone post a good, solid build with (fairly) early group travel (group flight+hover), generic IO's only (so I can start farming infl to GET sets) and a good, solid epic pool with at least one armor and either one mass hold, or one seriously powerful nova type power?

Again, the big problems I'm running into seem to be with what to place at what level, based on how many slots it will recieve, so I don't have to overslot or underslot things.

I'd like to see (but can live without):

2 or 3 slot hover
2 or 3 slot fly

My preference is definately for FLY instead of teleport.

My 'picture' of the build is flying over the enemy, dropping the minions in to establish tanking, then switching to hover and moving down into range to drop support powers.

Unless you can really give me a pressing reason why I would 'need' it...I have little interest in hasten, aim or buildup, or in tactics pool.

I really appreciate the help, in advance, and maybe if I see a good build I'll learn something.

An explanation of why you placed/slotted certain powers at certain levels would definately help.

I threw this together based on my experience with demons and the dark secondary. My level pact partner will probably comment. First I boilerplated in the default powers: (tongue in cheek) twilight grasp, summon demonlings, enchant demon, howling twilight, summon demons, hell on earth, fearsome stare, stamina, summon demon prince, abyssal empowerment, and the dark servant. Maybe a joke, maybe not, I wouldn't slot these any later than available. Then, I backfilled, tar patch, darkest night, crack the whip, hurdle, health, shadow fall, hover, fly, and group fly in the gaps. With the temporary travel powers from the low level mayhems, you should do fine until you can take the permanent powers.

Next for enhancement slots, I filled the demon summons ASAP. These are your attacks. I backfilled as available to twilight grasp, tar patch, howling twilight, etc as slots become available between the demon summons. There is truly a slot shortage until the level 30s so you slot the must haves: acc in twilight grasp, recharge in tar patch and howling twilight, endurance reduction in darkest night until your situation is alleviated in the 30s.

I gave some priority to howling twilight and hell on earth since these two powers can really break up the initial hits your mastermind group will take when striking spawns. This is where your dark secondary really shines.

thanks! It makes sense the way you explained it!
