I thought people might be exaggerating about SMN

Misses wildly? You gain your power from conjoining with an outside being with the ability to screw with your spiritual being while basing your damage around variations 1 ability and occasionally sending your pet out to do an attack. DnD Warlock with a Fiend Patron (Primals) taking Pact of the Chain to get your imp (Egi's) and spamming variations of Ruin (Eldritch Blast).

Final Fantasy's summoner predates the class first showing up in D&D 3.X by well over a decade, never mind 5e. The "XIV" at the end of the title isn't just because they think straight lines look cool, it means "Fourteen" and it indicates there were thirteen more of these games before this one came out.

edit: also, that's... not how XIV's Summoner works. Your Egis are created by shaping your own aether into a likeness of the power of a defeated primal. You are not making a pact with Ifrit or whatever.
