People are avoiding Sunqua. No joke.
The whole thing just too lengthy, it is too risky, the team may fail, and also sunqua is too tough.
I had 3 teams taking on Sorrowful Spellcaster, 7 attempts, none make it. Needless to say it spoits my entire morning/day.
You can consider taking out the 1st boss to shorten the Sunqua Peak, and then nerf the spellcaster.
1 spell caster fight is roughly 18 minutes. Now you multiply by 6-7 times. Plus getting to that area takes 25 minutes. That how much time goes into waste.
Seriously nerf the spellcaster pls, and shorten this particular frac.
