[MCU] Are Asgardians a joke when it comes to military power?

In the first *Avengers* both Thor and Loki consider the Chitauri a very powerful force. But then Rocket claims the Chitauri were “the suckiest army in the galaxy” in a deleted scene, and Nebulla does’t say anything against it. And in *Dark World* Asgard (save for the “big guns” like Heimdall, Odin, Thor, Loki, supposedly the Warriors Three, etc...) pretty much defenseless against the Dark Elves (who are using the same technology they did thousands of years ago) and Asgard has not been show to be much more powerful than perhaps Earth. So was Asgard in some sort of decline even before *Ragnarok*?

The Chitauri are impressive because of their sheer numbers... Numbers are important in war. One million standard soldiers are more useful than 1000 captain america. 
The dark Elves planned a sneak attack against Asgard and had ridiculous stealth technology that can bypass Heimdall eyesight and had black hole grenades with a supersoldier that can beat up Thor. 

The Dark Elves lost against Asgard in an all out battle.
