I thought that too until I really thought about it. If you take the original 7 warlords (Crocodile, Jinbe, Hancock, Moriah, Mihawk, Doflamigo, Kuma) I think that together they could take whatever the Marines or Yonko's threw at them. With the Marines we've seen that if Doflamingo was to leave the Warlords at least one Admiral (Issho) has to be sent for any kind of victory. In OP we have seen Doffy and Crocodile clash on pretty equal terms which means that an Admiral should be sent for Crocodile too. That means you have two of the strongest Marine powers tied up with only one more to allocate for 5 Warlords.

For Yonko its different because the only one in any real detail that has been shown is Whitebeard but even then all the Warlords were there and fighting and all lived with Croc, Doffy, Mihawk, Kuma and Doffy taking practiacally no damage. I feel that together the Warlords probably could match the marines and at least one Yonko.
