Auto attack: A complete battle system

[Teknoman]

Like what? Honest question, since the only one I know of is Vindictus. I think even Guild Wars 2 is going the auto-attack route.

Another one that's actually available is DC Universe Online, which has a great combat system without auto-attack. The game has a lot of issues outside of combat though, I wouldn't recommend it without a trial first. Actually I wouldn't recommend it at all, as it will seriously spoil your experience of combat in the classic MMOs.
The strongest contenders for action combat MMOs are still not available, Blood&Soul, GW2 (not really auto-attack, but a toggle system, and VERY dynamic) are all still in development, TERA is only out in Korea.

You pretty much nailed all of the games I would have given as an example.
