What is parsing?

[Lateralus04]

I cant tell number by number no! Of course not!

Normal environmental awareness, absolutely yes!

This seems like something that may keep the community quite divided if parsing is so important for progression...

There is nothing wrong about being exclusive and wanting only to play with the best players you can find. I personally don't do any of the savage or extreme content, but it's 100% understandable why someone would want to be exclusive so they can finish the content faster instead of carrying someone who underperforms, and that is why parsing is important, so you don't waste your time on the player that drags down the entire raid.
