No because Natsu never picked up any boulders at all at the time, and also didn't figure out the con of his magic then. And Franmalth can absorb anything magic-based, that's how his magic works and Taurus is a Celestial Spirit who are indeed magic entities, it has nothing to do with him being weak, he can absorb any weak or powerful magic and becomes more powerful himself which is why Natsu had a hard time in defeating him until he found out that he can't absorb any non-magic based things such as a boulder which btw he couldn't have done if Lucy never had tricked him to think Natsu was a Celestial Spirit.

Well Jackal appeared behind Loke whose attention was all on protecting Lucy more so than worrying what will be behind him. And besides that, he implanted a bomb on him in once again a very vulnerable location which so far we've seen, somebody like Natsu being a Fire Dragon Slayer can withstand it and another thing is like you said, there's no way Loke would beat him because of him being a melee fighter which is just a easy way for Jackal to win. And Aquarius was owning him till she got injured as you saw but do seem to be the only spirit to be able to take care of him if she wasn't hurt that is.

But at the same time if it wasn't for Lucy, Natsu would had never fought Jacob and would've been with everyone else and also dead. And she had nothing to do with him not using FDKM, that's all on him choosing not to and only b/c it would melt the guild to nothing. And it doesn't show any signs that it'll do any harm to her unless she's hit by his attack except it'll only melt away her clothes which he could careless of anymore. *shrugs*

You got a point on this part, Erza and Lucy would look good fighting together while with Natsu, she do seem to be of good support more so than help fighting.

Oh. My bad ^^. But Lucy been sometimes rescuing Natsu
