New Justice League Team! Are You Happy?

If you've read issue no. 7 of the Justice League of America, you might be a tad surprised. The story arc begins with Superman, Batman and Wonderwoman selecting members. And at the end of the story arc, they just choose who's around them when an incident occured. Among the new members are:

Superman!

Batman!

Wonder Woman! ( Why am I not surprised?)

Black Canary!

Vixen! (She's cool. You can keep her.)

Red Tornado!

Black Lightning!

Green Lantern!

Hawkgirl!

And Arsenal! Huh? Who's that? Make him cool all you want, but Green Arrow is still cooler. Who decided to substitute Green Arrow with the former Speedy? Hope you kill him quick!
