Hardest raid encounter on this server?

[Erati]

if they made ToV dragons unslowable - holy moly things would be far more interesting when encountering them

Cazic Thule should get a mini shout out here as he is a major pain in the ass and will beast on any unprepared raid force. I feel guilds have wiped to him more frequently than most non-Sontalak or AOW encounters. Sont/AoW are a bit overtuned so the margin for error is slim to none, Cazic can be overcome with some good raid set up and execution.

Slaying him cleanly probably still one of the most fun and satisfying raids bc its all about executing the strat and surviving from 100%-0%.
