Spoilies!
G'raha is the protagonist of the CT storyline, but he is not the hero. We are always the hero, but because almost no storyline in the game examines our character or leaves us personally responsible for much of anything that is happening, we are almost never the protagonist. We just beat up whatever is in the way of the real protagonist's / protagonists' way that's preventing them from fulfilling their goals.
Case and point: G'raha. CT is his story about how he was bullied as a child and has sought the reason behind what his father said and his connection to Allag. We help him achieve that goal by exterminating the inhabitants of Syrcus Tower, but that might not necessarily be our goal. NOAH's goal starts out as "for research" and transitions to "to protect the world from someone abusing Syrcus Tower," but the Warrior of Light has no personal investment in how things turn out. (Unless you, the player, come up with one yourself.) Aside from being a giant stick that can be used to whack whatever gets in the way of the protagonist (G'raha) from realizing his goals and getting his character development, we aren't needed.
3.0 has a similar dynamic. Alphinaud, Estinien, and Ysayle form a 3-man band, with Alphinaud as the realist, Estinien as the pessimist, and Ysayle as the idealist. They all have their character development (though Alphinaud's is minimal, given 2.x's ending marked a massive change for his character), and we are along for the ride... but contribute almost nothing to the story except dead bodies. Alphinaud wants to help Ishgard end the Dragonsong War in return for granting us safe haven; in spite of everything thrown at him (and us), we succeed. Estinien wants to end the Dragonsong War because he hates all dragons and wants to kill them, but gradually becomes slightly more idealistic and only does so when it becomes absolutely clear there is no other option. Ysayle starts out as an idealistic "if we excise the Church the dragons will be happy" woman, but later seems to accept that Nidhogg is (or was) a deranged psycho who had to be put down.
If you take out primal fights, the number of times you are personally necessary are extremely small: at the conclusion of your city-state intro quest because there was nobody else around, at the end of the Praetorium because you're the only one bad enough to go toe-to-toe with Gaius and your Blessing lets you take on the Ultima Weapon, against Nabriales because there was no one available, and at the very end of Heavensward because everyone else was busy.
Ultimately, the point is being the hero does not mean we are the the protagonist. To use a pop culture reference, Light Yagami of Death Note is not the hero of his story, yet he is still the protagonist. We just butcher whatever is in the way of the protagonist(s), thus setting the stage for them to fulfill their goals.

Ehh... maybe. But remember that a primal's strength is dependent on the quantity of crystals used to summon it; base Ifrit, for instance, is pathetically weak because he had very few crystals to fuel him, something Nero takes note of after the fight. Once we get to Titan though it's implied that almost nobody has beaten him before; the Company of Heroes did so using human wave tactics and at a heavy loss, and they're all hardened badasses (supposedly...).
