The Zeros part absolutely is stupid. The females are all pretty damn solid; I liked Haleh and Surigosa best and Azuregos is excellent. As for Lanigosa it was just a massive improvement from her last appearance. The finale with Senegos is solid. The fight vs Sindragosa was just dissatisfying because it reminds me that Blizzard cannot bother to scale shit (and given I'm a 430ilvl tankadin if it was built for me, most people would just die), like she kept casting but nothing happened.
I think the reason it is well liked is that it is pure fan service. It has a large roster and visits multiple locations. It's the exact same reason the Orc Heritage one was liked. And imo it shows how a revamp would also be well liked but that's another topic.
