The rest of the members are ridiculously powerful. Atom can split himself into millions of himself, Resurrection Man can take on any power and is one of the best strategist in comics, even besting Superman with ease, Batman has tech to steel souls, Aquaman can transport planets filled with water across interstellar distances, Hourman has a piece of the Worologog, etc...
The only ones that weren't that impressive are Wonder Woman and Flash. Though, Flash can run faster than the speed of light and time travel, IIRC.

Worlogog?
Pft... That would be useless against Prime and would probably get controlled by Henshaw.
I don't know exactly what we can call "established" team and "non-abstract". There is that team of Skyfathers that teamed up to beat the Celestials, or the team of villains in the original Secret Wars (they had Owen Reece, that's pretty much it).
