Honestly i would say nefer's, god it was so draining and LONG! i'll say it took me TWO weeks to finish it along with the archon quest, y'all know that rerir scene where he was signing the papers? we did the EXACT same thing with nefer, except we didn't even sign anything and we only looked at the letters, there WAS a letter i kinda agreed with, but that's not the point.
Her story quest was literally just shoved in and i feel like it was just made last-minute, the most cringy scene was nefer laughing her ass off and thinking of herself as a liar's little girl after the two tribes were dead.
Oh and don't even get me STARTED on when nefer said goodbye to her friend she had the nerve to think, "oh i'll forget about you anyway." like girl wtf was THAT? honestly they did her dirty, they literally made her the most insufferable character in just ONE patch.
Apparently the archon quest + story quest plan was SO bad of an idea, hoyoverse didn't do it with durin's story quest.
Anyway, i don't remember anything that happened in nefer's story quest except for the parts i mentioned, and thank god i don't.
