My issue with Ranjit is that his power source is so poorly defined. He has a dragon familiar junctioned to him. Ok, so how does that dragon compare to say, Nidhogg, in terms of power? While we did have the eye of Hraesvelgr to boost our power, I doubt the wyrm Ranjit used was on either Nidhogg's or Hraesvelgr's power level. It is implied that you and you alone with the eye empowering you are able to take down Nidhogg at his most powerful.
The quest text for the Final Steps of Faith:
Imbued with Hraesvelgr's last sliver of hope, you stand at the forefront of your allies as the last bastion against the raging shade of Nidhogg. Have you the resolve to conquer the great wyrm at the height of his power, or will Ishgard perish in fire and ruin? Here, on the battle-stricken Steps of Faith, your deeds shall decide how the final verse of a thousand-year dirge of grief and vengeance will be sung.
Some will inevitably say the standing at the forefront of your allies bit means standing with the seven other players, but we were defending Aymeric and his knights retreat.
Adding to that, the strongest heroes in Norvrandt each had only one crystal of light. We alone have six which gives us The Blessing of Light and the Echo which allows us to see an enemy's attacks before they go off. The argument that his is a fighting style unknown to us pales as an explanation because the reverse is true as well. We had been chewing through demi-gods for the entirety of our career as a Scion member on the Source (and even longer as a legacy player), while he was putting down rebellious farmers for decades who only wanted a future for their children. He couldn't even kill a Lightwarden for the previous Minfilias so they could absorb their aether and bring an end to the flood with an entire nation's army at his back, we do so with four people, canonically the Scions. To flesh him out, far more context is required for him to be even thought of as an equal. Just because you have been doing something your entire life does not mean you are the best at it. We punched his clock within a weeks time of being on the First.
Oh, that's also without noting that we had just gone toe to toe with a fully realized Ascian, one of the three most powerful beings we have ever encountered with a thousand thousand lifetimes (sorry I just had to) of experience fighting for their people with unwavering conviction (which he lacked by buying into Vauthry's idea of paradise ie: suicide by apathy), in the body of one of the most vicious killers in the history of the Source who wields the Ama-no-Habakiri, one of the deadliest weapons in Japanese myth that Susanoo (a storm god of Shinto origin) obtained by slaying the demonic eight headed, eight tailed serpent Yamata no Orochi. We surprised him in such a way as to render him shocked at our strength and only lost the second go around because of bad timing by a certain Exarch. Which i'm glad they noted Alisaie as being upset about said timing and giving him an earful.
So, who is Ranjit in the grand scheme of things? No one. Nothing. And that, that is the issue.
