I think people are overestimating the "roaming" portion of the Roaming Primals system. I really don't think it means they will be roaming all over different zones, just that they will be in the open world.

I believe that Ifrit will "roam" areas of Zahar'ak, where his tribe is. You'd have to fight through Zahar'ak, and maybe try to claim Ifrit while surrounded by enemies, at which point your whole party would be "Drawn in" to the Bowl of Embers.

OR, the Bowl of Embers area will become available as an actual area, where Ifrit will be roaming around, and you'll have to claim him there, at which point you enter the actual instanced version of the fight.

I'm ok with this. Contrary to what Rokien says to lie to himself, lag WILL still exist in some form in 2.0. And because having too many characters on your screen lagging you down is more PC than network, it WILL be a problem if too many people come to watch the fight.

"You know you can turn off the number of characters displayed". Yea, because changing my settings during every fight should be a requirement to prevent other people from getting me killed.

Keep the claim open world, keep the fight instanced. I like the track you're on Yoshida.
