I like it!
1. Diana's in a leadership role, with no Superman or Batman to be seen.
2. Diana and Zee together is ALWAYS good.
3. Detective Chimp is awesome, though I do agree with Agent Z that I'd rather see him in a reformed Shadowpact. And to anyone wondering what he can do? He's Batman the way Batman should be on a Justice League team: he's the brainy investigator who collects valuable information for the team. He also appears to be carrying a sword in that pic, so I'm guessing he'll be at least somewhat combat capable.
4. Glad to see Zatanna rockin' the top hat again, though yeah the rest of the outfit is a little too New 52-y to me.
5. I did notice that Manbat isn't magic-based, but that's not a huge problem. I kinda like having at least one science person on a magic team. Always funny watching them stress out trying to rationalize what magic does in a scientific context. Plus, he brings a fresh perspective.
