you missed the entire point of the post.
That post was part bugs that can be easily avoided, part people being scrubs and killing themselves then blaming it on bugs, and part not figuring out/reading up on boss abilities.
Having some patience, being organized, and paying attention will get you far. My first EV raid had only 1 person with experience, we killed every boss on the first attempt except Soa, who took 2 or 3. Killed the Rancor right after.
