So riddle me this. Let's say for arguments sake, that everyone in your savage group is doing all the mechanics perfectly 100%, but your wiping every single attempt because someone in your group's damage is way below the mark to beat the enrage, who is accountable here? Parsers are a two way street, they benefit the game through feeding the player base information on optimal rotations, melds and help the developers by means of a visible display where all the jobs stand in the most difficult content, but they also tell you how your entire raid is performing and if adjustments need to be made. It can help those who are struggling perform better and in worse case scenario ( The one point that has been the focal point of contention between the player base for years) replace those who are under performing and are showing no signs of improvement.
