I do think Starry Muse was an issue. In a lot of high-end raids, precise positioning is extremely important, and starry muse is just way too big, and obscured way too much of the arena. All for a buff that only applies to one member of the party.

No other ground aoes really have this issue. Most mitigation aoes are relatively light. And as for ley lines, the fact that it's smaller, levitates off the ground, and slowly spins makes it not an issue to see the ground in limited.

I was happy to see it gone, but I never really considered it from the perspective of someone who only plays in limited. Kinda makes me wish there was some sort of compromise, like how ASTs star aoe works- where the starry outline is visible in limited, but the full explosion isn't. Maybe they could've kept the outer ring of starry muse visible, while hiding the pulsing flowers.
