Need help- Raja/Rani requirements Follow

For Raja it says "Trade KeyItemShattered Iron Giant Chain and KeyItemWarped Chariot Plate to one of the three ???s at (J-5).
But also

100% intel on T2 NMs Ironclad Sunderer and Assailer Chariot is required for the ???s to spawn."


The Ironclad was 100% when I checked with the dominion npc but the Assailer was only 50%. I died the first time trying to kill it but managed to kill it the second time. Then i checked again and it went up to 53%. So am i missing something or will i need to kill this thing almost 20 more times just to be able to summon Raja?
Im guessing someone must still be killing the Ironclad for it to be at 100% but i dont really know how it works. Im usually the only person in Abyssea Grauberg when im there.

Thanks for the reply, I might go through with it but atleast for now I know theres no trick im missing.

Sorry but im on Carbuncle, thanks though.
That being said I found that they must have changed the spawn requirements for the Assailer. I killed it earlier today and then started to do Ops 3 to get it to 100% from 50. But I only got a few done before it popped again. Looks like it pops every ten minutes or so regardless of Ops 3 now so that makes it a bit easier.

Yeah, as far as I'm aware those Dom Ops requirements were never related to the time spawned NMs at all. It was, at least at the very beginning, the requirement for the actual ??? to appear.

I want to say though that before even Voidwatch came out they lessened if not outright abolished that requirement.
