All of your examples are subject to the checks and balances shabbadoo raised earlier, moreover...for example:
What exactly are are of these "true" close combat units that leave Assault Marines as a smoking pile at the starting line?
Poor armour and expensive upgrades. Also, according to the background they should be better than most things in close combat. Not that I ever expect you to let the facts of the background trouble you.
Elites choice, without upgrades these cost the same per model as Assault Marines (4 points more to get Rending weapons) and they're Toughness 3, have a 5+ inv save and aren't as mobile as Assault Squads. Also, according to the fluff they should be better than Assault Marines...
Toughness 3, 6+ armour save (4+ dodge, whoopy), expensive upgrades, NO Rending, only Hekatrix gets power weapon (or power weapon like upgrades).
Dark Eldar Chicks...
More expensive than Assault Marines, expensive upgrades, almost double the cost per model of an Assault Marine if given a jump pack... and they're 0-1.
Over double the cost of an Assault Marine per model, expensive upgrades, and capped at 5 models.
The only unit in the Ork Codex thats better than Assault Marines model for model are Nobs and Meganobs, which are Elites choices (one can be included as Troops if the army includes a Warboss).
Orks have a unit that does also...(cant recall name, but the orks do it a lil differently than the others, they use brutality and toughness)
If you can't list them, don't ask us to assume that they're there.
I know there are more, but I do not have all the 5th edition codexs.
For me this is about making a fluffy unit, not a beat all comers tar-pit unit of doom. Meaning there will be units out there better than it, but they're still one of the best all around cc units pound for pound.
The ones I am pretty sure do not are IG and Tau.
Not sure about necrons.
Basically any unit with 5+ Init, 5+ WS, 3+ attacks, High Strength or access to a lot of NO-Save/Rending CC weapons, such as pwer weapons, harlie-Kisses, scything talons, etc...Or with an assortment of Special rules, FC, CA etc.
If this is about a proper fluffy DA Assault Squad thats one thing, but what alot of people are asking for goes way beyond that, its diving headlong into uber unit of Doom territory.
People investing so much time and energy on units like this (which should be a quick and simple excercise in copy, paste and substitution) rather than sorting this quickly and moving on to more interesting new/uniquely DA units, seems like a massive waste to me.
