5 reasons why PS4 players need a parser in game

[akaneakki]

Might be wrong, but I don't think anyone's claiming that having a parser means that you no longer need to learn mechanics, a rotation, or how to coordinate with your group. A parser simply gives you a number, and from that number you can tell if you're on the low or the high side. If you're on the low side, you can then go "well, I must be on the low side for a reason, let me examine what I did in the fight and where I can improve". Then you test your theory on how you can do better and if the number goes higher then you've improved. Without knowing that the number was low in the first place you might never have realized it was an issue and continued on doing what you were doing before.

^ This very much.
