Hmm, yeah, we do have those two. As for Legion worlds, I'd be curious to see what Blizzard could do with that. Argus - in my opinion - would be the most probable of Legion worlds we'd go to if there were going to be a Legion-world expansion, given the rest are random planets throughout that we've never heard of, while Argus has been a piece of lore since BC and such.

As for the 'end-goal', that seems possible, but yes, we'll have to see what happens going forward.

And... Regarding artifacts. I'm not exactly sure what Blizzard will be doing going forward with artifacts, however I really wish in Legion they'd of toned down the massive lore "breaking" aspect, given the players are appointed really major roles (like the leader of the SH and wielder of Ashbringer) that well, at least in my opinion, should stay filled by NPC lore characters. Though, that aside, I think something like you said as a form of horizontal progression may be a good route to take if they're going to keep artifact weapons flowing with the next xpac.

Thanks for the input on the topic, Aretain.
