This is not a question of "need", high parse, high players everything you knew in a game will be in a instant distorsed, hold your chair: there is no skill in illimited timed games. Well, at equal playtime there is but 80% of games is gear / playtime. Fun is what attract the first, you know you can't "parse" very high if you don't have the dedicated playtime, I was in before I know my words. Now I'm parsing 80%~ for all DH reports but I have 880 gear cause I don't raid mythic, this makes it a good perf because it's not with the same used to group with high perf too (obviously making top parse easier mathematically). Could I parse 95% ALL ? No sorry, impossible there are far more geared players above. For my ilvl I parse always 95%+ but we don't care when everyhone speak about "top parse" so stop linking you ***ing parses as a justification of "skill" and "insult".
If you want skill, there is IRL's high difficult jobs and stop insulting people who don't fall in your opinion case, crit/mastery matters a little if ilvl difference is here with main stat scaling. "L2P saying people" should go back to real life and learn some mathematical / logical course cause they are spreading bullshit.
And I already answered before as far as "fury starvation" perception is about. People who don't speak about starvation have either heavy gear crit oriented to leverage probabilities OR don't have the same perception of the concept of "few sec without fury and CD to spend even FR / TG and even if it's rare in a fight".
I hate injustice between people and high empathy makes me answer.
