No offense but I wouldn’t really call this a ‘MasterClass.’ It’s a good summary for anyone interested in picking up the job for the first time, or as a basic refresher for roulettes, but you don’t cover anything related to harder content, how to be an effective off-tank, stuff like that. There’s also things that are wrong/could be expanded on, i.e. mitigation being multiplicative instead of additive, Passage of Arms lasting 5s after being canceled (no need to keep active, just flash before a raidwide), etc.
