As I said before, us fighting Argus which is essentially a titan equiv to a premature birth. He's so weak comparatively to Sargeras himself its believable we can *fight* him. Sargeras on the other hand couldn't be fought. "BUT THE TITANS CAN EMPOWER US." They weren't in a position to do so, perhaps if they retained their original bodies it might of been possible but it would still be a bit absurd).
Sargeras is the big villain pushing Legion's narrative via Kil'Jaeden and every demon invading. Its fine to not fight him at least his pure raw power.
Argus wasn't even half as interesting or well-developed as Gul'dan or Kil'jaeden and yet he was the final boss of Legion.
Actually he was, he ended up being from the planet the Draenei were born on, their homeworld and basically a sentient generator for demons to regenerate like *Snaps fingers* that. Tortured for so long and abused for Sargeras's plans. The bad part of it all is how little time we have for that to sink in.
Maybe, it depends how it plays out, I still wonder if Nathanos is gonna die loyal to the Banshee Queen or any regrets or something like that. Either way, I'm sure Horde players want to shut his face once and for all.Nathanos likely dying first raid is not a good sign of Sylvanas's life expectancy IMO. It's one thing to him to die in the Torghast raid as a sub boss while she runs away, but if he ACTUALLY dies in the first raid... which is incredibly likely...
