What doesn't make any sense in your codex?

There is no doubt they are tough, and defensively, they are one of the most powerful Troops at this time. But when talking in general, they are meh on Offensive, which brings the combined force to good, but not most powerful. Especially with Draigo running around.

[Still Standing]

Well, 2 plasma guns, a plasma pistol and powerfist is nothing to sneeze at offensively... Especially when they can withstand the overheats.

And there are how many Marine Troop units that can match or exceed it? That's why their offensive capabilities are just meh.

[Mr Zoat]

How about an imperial commissar executing an allied Magnus Calgar for failing a leadership test?

That's the best piece of 40k fluff I've ever read, official or otherwise.

That would have to be my favourite Space Marine themed story ever. :'D

In a squad of less than 10? None off the top of my head, unless you start using purifiers or loganwing.

2 special weapons in a squad of 5 troops isn't that common. Templars do get las/plas but no pistols/cc weapons in the same unit.

A thrown singing spear is able to enact full-field distortion effects that would make it suicidal to hold. When held, the spear re-contains and limits its dissonance and so is less effective as a melee weapon. Much like, if you were to engage in melee using a grenade as a club, it would be potentially deadly but not nearly as effectively lethal as when it's thrown and triggered.

I can't help but feel you're intentionally missing the point here.
Suppose you throw your singing spear at a tank, it cuts through the armour like cheese and goes boom, now throw your spear at a tactical marine, somehow power armour is as hard to penetrate with a singing spear as it is with a las round, so much for "full field distortion effects".

Daemons = Bloodletters etc. Yes, you can have them in your army, and for most of 40ks life you've been able to.
Cult Troops = Plague Marines. Nothing Marines have (except Grey Knights) is that powerful.
Extra Powerful heroes = Daemon Princes, 3.5 Ed Chaos Lords, 2ne Ed Abbadon.

You don't think the separation is anything new, do you?

Wow, going all the way back to 2nd edition? lmao, I'm like, lmao
And 3.5E Chaos Lords...

Your list is slowly falling apart. Daemon Princes are good but Mephiston and Draigo would absolutely annihilate one, plus their stats are pretty much the exact same except that Draigo has a 3+ invul and tons of psychic powers.

Bloodletters aren't that great now that they don't ignore Terminator armor. Plague Marines are pretty tough but Death Company comes very very close, and they're less expensive in points

Nope, not intentionally. I didn't think of its thrown effect upon power armor

You can get two winged princes for the cost of Draigo or Mephiston however.

Death company are a product of the 6th ed rule change where their main balancing factor - uncontrolled movement - has been replaced with extra attacks in close combat. And they are still not scoring troops.
