It's really not nonsense though. Think about how juiced up on external power we had to be just to beat a couple of broken Titans. We were probably the most powerful mortals the universe has ever seen at the point where we barely managed to eek out a victory over Argus (and yes, barely, if Eonar hadn't been there we would have been one-shot like a bunch of idiots holding plastic swords).
If you look at how comparatively easily we subdued Denathrius, it's quite the joke. If we had our powered up artifacts and Titan buffs at this point in Shadowlands the Jailer would already be dead and we'd be getting ready to head home.
The Eternal ones are quite literally a joke when you put them next to Titans. I mean the Archon would have lost to Devos 1v1 if we hadn't been there, then we proceeded to absolutely destroy Devos in a 5 man dungeon. The Eternal ones are lucky that we turned out to be good guys, cus we could have just waltzed through that portal, fucked them all up and taken Shadowlands for our own without breaking a sweat.
I've yet to see any epic and powerful representation of an Eternal one in the Shadowlands that puts them up there on the god-level of a Titan. Right now they all just seem like whiny demigod level creatures of which we have dozens on Azeroth. They also seem like they are almost nothing without their sigils, which means their base power without that magical artifact is probably more on the level of an extremely powerful mortal on Azeroth. They are 5 man dungeon boss level at worst, disappointing raid boss level at best.
