While it is a bit surprising they require completion of the EW MSQ it isn't unusual. Everything is gated behind the MSQ, for all we know the island is tied to Sharlayan in some way. Though that is a stretch, and I do hope others can still visit regardless of MSQ completion.

As for Steps of Faith. That instance needed the adjustment. I mean, you could already practically solo it at level without breaking a sweat with how hard they had to nerf it because people kept complaining about how hard it was. I cleared it day one, and while it was a challenge the challenge was really only in getting a bunch of randos to communicate and work as a team. Can't really blame SE for that, that one is on the players for refusing to do the group game play thing. At this point it is just easier to make it a solo instance so they never have to worry about someone complaining about it again (though of course someone will).
