sorry about the links beforehand
Just like the title says. If you connect the dots, it makes so much sense…
Quoting someone from Reddit here;
"I personally agree with this theory because I mean, the Runecarver fits the description of the Primus near-perfectly. We have a master blacksmith/runeforger who was known for his amazing weaponry and leading abilities.
We have this character who looks similar to the only statue we’ve seen of the Primus who has no memory but displays insane runeforging and blacksmithing skills, enough that if we can provide his missing memory, he will build us armor unlike any other."
Other reasons are:
1. The Primus has been gone for a long time and The Runecarver has been in Torghast for a long time.
2. His memory has been wiped so he wouldn’t know if he was The Primus or not.
3. The visuals look pretty similar. There is a statue in the (I give up on grammar) seat of the primus that contradicts this, which looks like this:

In this statue, you see that the primus has antlers and 4 fingers whereas the runecarver has 5 fingers and no antlers. However, I don’t think that this is an accurate description. If you look at the big statue of the primus, you will see that he has 5 fingers and no antlers.

Quoting another person from reddit:
“Also, Maldraxxus is where the scourge originally comes from, and the runecarver is the one who forged the helm of domination and frostmourne. Both these guys have connections to the lich king”
Proof here: ‘https:/ /www.youtube.com/watch?v=m6wF6KiwCAw’ (skip to around 1:00)
and another quote:
“In french both are voiced by the same actor, both are extremely talented craftsmen specialized in runes, the runic blade of the Primus looks like a proto frostmourne, the size of the guy is about right, his body wouldn’t look too out of place in Maldraxxus… And he is amnesiac” This could just be a coincidence but I don’t think it should be overlooked…
Also, if you skip to 0:55 in ‘https:/ /www.youtube.com/watch?v=GgFxswxKWpk’
You will see that sylvanas says us players breached the seat of the primus and discovered his message, and as she says this, it shows the room where the primus is.
This can not be a coincidence. I am 100% certain that the runecarver is the primus.
