Its not needed at all, only for those who are scared they are under preforming and want to know exactly where they are on the scale.

Im a ps4 player, and a strong believer that practice makes perfect.. if you dont hit that dummy and try new things you wont really get far at all. i dont need someone to tell me how much dps im pulling or whatnot since this tier isnt really about how much dps your pulling its more mechanics heavy imo, its the same with guides and such players tell me that i SHOULD watch a guide on fights to get a better understanding, I disagree to this because guides now days feel rushed and are more about the view count then actually teaching the player the fight. plus going in blind with a full group of FC members, Static, PF (if you note its a blind run) or just friends in general its darn fun, give it a shot this tier its actually better to learn for yourself then be a sheep and copy others, (which i know your not fond of from your glam thread)
