Yes? Maybe even more powerful, so what? Still not nearly as powerful as argus or aggramar.
I mean at this point there is so much evidence pointing to the fact that the champion is ridiculously powerful.
But let’s get to the obvious, artifacts and heart of azeroth, now, would you give such powerful artifacts to your run at the mill adventurer or to the strongest person around? I would guess the second.
Second, it’s directly stated in some of these artifact lore, that really powerful canon characters were not able to control or fully use the artifact to the maximum potential, one example, is elemental shaman fist of ra den, Lei Shen was not able to control this artifact, you have to understand that Lei Shen is ridiculously powerful.
Third, the artifact was selected at the start of legion, end of wod, by the end of wod, our characters were already at the apex of their respective class, by the end of legion i would assume they got even more powerful, probably at least twice as powerful, at the very least.
I mean, there is just too much evidence pointing to the fact that the champion is not to be trifled with, at this point it’s in the top tier in terms of power in wow. To deny it, and say that the champion is really not that strong, or, to say that they are strong only because of their artifacts, is ridiculous and disingenuous.
