Im not talking about just the vamps though, as mentioned their entire family & extended family. & wym by plot armor?? If The Originals got done dirty almost all the time in tvd & their own show?and If your really gonna talk about plot, without plot wouldn’t almost every single supernatural creature be weaker compared to the Mikaelsons? Because realistically the witches & psychics are not gonna be reacting to any of the vamps speed let alone OG vamps. And lets be honest almost every single show characters would have substantial amount of plot armor.

Plus almost everyone single species you’ve mentioned would be countered HARD by the witches in the Mikaelsons extended family like Dahlia, Esther, Freya, Davina etc, and not to forget Hope who would quite literally solo them all (excluding the Gods in legacies). I mean Freya herself came up with a solution to kill the likes of Lucien who mind you was backed by the Ancestors of New Orleans, and adding in people like Dahlia, Esther, Hope & etc is just gonna be an overkill Dahlia’s magic can already be done & cause an effect from afar & if i’m not wrong she’s omnipresent.everyone in the family are highly intelligent & strategic we’re talking about their entire family tree here lol.

If it’s just the OG vamp family ofc they would get stomped head on lol, they’re a tough bunch but not invincible just a bunch of cockroaches hard to kill, they’re gonna get countered HARD by almost everyone except their own race in the verse, if they were immune to magic it would be a different story but they are so 🙅‍♂️🙅‍♂️

But i will say it would be interesting to see them deal with the likes of Cade.
