New Avengers members; no more original characters?

So I've revently noticed that since New Avengers debuted, there have been no original characters that have joined an Avengers roster. That is to say, no characters created in an issue of the Avengers have gone on to join the team. Ever since New Avengers debuted, there's been this pseudo Justice League vibe, that the teams are formed of well known characters, many of which are not from an Avengers background.

In the old days, if the writer wanted to add a new member to the roster, they would created them. These days though they're plucked from another title, or in some cases Comic Limbo. I'm curious whether people think this is because:
a)The writers (Bendis mainly) are afraid people won't take to a new creation as much as they would an established character; or
b) Bendis is making a conscious push to maintain that psuedo Justice League vibe for the team?

Hell, perhaps you think its something else entirely, I'm keen to know.  Also do you think we should start seeing some fresh, original character blood on the teams? My fear is that if we continue down this road, eventually everyone will have had a turn as an Avenger. I mean at the moment we have three X-men, Spider Man, a member of the Fantastic Four and a Hulk on the teams.

Here's just some of the characters that have joined the avengers since Avengers Dissembled:
Spider Man, Sentry, Wolverine, Luke Cage, Spider Woman, Echo (though the Ronin identity was new), Jessica Jones, Iron Fist, Doctor Strange, Ares, Stature, Young Vision, Bucky, Protector, Thing, Red Hulk, Ant Man, Moon Knight, Daredevil, Storm...The list goes on

On the flipside, how many characters pre-Bendis were created to join the Avengers? None really come to mind.

Black Knight was a recurring character who had debuted in Avengers, then had a solo UK title adventure, and then joined the Avengers. I think...would that still count as a created specifically created to join the team?

Looking at that, there's a number of 'legacy' characters there, Cap, Ant Man, Yellow Jacket and Black Knight were all successors to the code-name...interesting.

I think it boils down to the whole "there are so many characters out there that are not used, why create more" mentality.. I mean look how most fans react on here to the new characters showing up in x-books instead of older characters like the x-kids being used.

Holy crap. And even Prince of Orphans is a retake on an old character.

I am all for there not being any new hero's join Avengers. They are ment to be the best, able to handle the situations on one else can... so that means a character needs to prove themselves first. I think like in the 80's there were some very mediocer heros on the Avengers lineup - Mantis, Tigera, Triathelon, stingray, swardsman. I mean any rag-tag team of villans should be able to deal with them.

lol yeah she will

Mantis was on Earth because she is a human being, not an alien.

It's supposed to be a hairstyle. In recent years, though, artists have started drawing it like she has actual antenna for some reason.
