No it simply stood as an argument to show that you dont NEED to be NF to clear content. Only 3 boomkins that are necro still managed to clear it, meaning, you dont need to be NF. It it harder? Yes. Are the numbers lower? Yes. Did bringing a necro boomy offer a different kind of utility? Also yes.
I wish people would stop saying the are cov locked because if it were actually true, there wouldnt be a single off meta cov in any content. Unless of course what they are saying is “im not good enough at my class/spec that i need to give myself the largest advantage to clear content, even if i dont enjoy it”.
Enjoyment of game > what the meta says, especially when you dont enjoy doing what the meta says.
