No they weren't.

Natsu was pretty much chanceless against Zancrow until he did something that shouldn't even be possible.

Wendy was on the verge of collapsing while Chelia was still fine and the battle only ended in a draw because they spent as much time for talking as fighting and thus hit the time limit. Sure comeing out "only" equal to Juvia didn't make her look all that good, but then Juvia is far from "pathetically weak" so coming out equal to her (and when she's in her "I do this for Gray-sama" mode to boot) isn't a bad thing either. Besides with her kind of magic Chelia is already a support/offensive hybrid. And she's quite young too, so there's quite the potential for groth. Being grounded by Bluenote isn't exactly pathetic either, if that's what you base your opinion on.

Orga is quite the monster on the offensive side and was even able to go toe-to-toe with Laxus for a little, until his lack of defense was exploited by Jura. Quite far from "pathetically weak" if you ask me.

As for the original question, I think it's pretty clearly Orga. His greatest weakness if probably his arrogance. If he hadn't let himself be goaded by Jura, the fight might have taken a few seconds longer. :P
