Theory Crafting: x4 DK + 1

I've got three, but mainly use two priority sequences.

A) Howling Strike -- Howling Strike > Frost Strike > Necrotic Strike
This has Mind Freeze built into it, as close to one Mind Freeze on the kill target, every 2.5 seconds as possible.
It has IWT for the melee toons, on every press.
It has Howling Blast on Press.
It has Howling Blast x1, Frost Strike x2 and Necrotic Strike x1 on release (meaning 25% chance for HB, 25% chance for NS and 50% chance for FS, assuming it was on GCD on a press and is not on a release).
If on a given press or release, the rune is not available or the runic power is not available nothing happens.
I spam at 2.5 clicks per second, so 2.5 down events and 2.5 up events per second.

B) Obliterate Spam -- Obliterate > Frost Strike
This also has Mind Freeze and the IWT, on every press.
This is combined with the Hungering Cold, which I manually manage.
I will use Outbreak with this, as Obliterate hits harder against diseased targets.
I use usually save the Runic Empowerment for this one, as it is another three Obliterates in quick succession.

What is the conventional wisdom regarding gems and enchants for a 4 DK setup?

It seems to me that the conventional wisdom regarding solo DKs that resilience is still an excellent stat, and if you look at the top DKs, you can see 3600+ resilience.

Does that sort of strategy to gem/enchant for high resilience still make sense for 4 DKs? Or is still just more about Str/haste (after capping hit and spell pen) ?

I've gone with:

Red = 40 Str
Yellow = 40 Res.
Blue = 50 Sp.Pen

So far I've got just the right number of Blue sockets.
If I had an extra blue socket, I'd probably go 60 Sta.

I put a 40 Res gem into the prismatic socket on the bet.

I have nearly 3700 resil... resil helps... A LOT
