My group is mostly ps3 and ps4 players, only one of us uses a pc. He got a parser to help with the boss' hp to know when phases change. We have never kicked a pug for lack of dps. I can see how it can and would be used that way. I am competitive though and would like to know how I'm doing compared to others. They will never be officially supported because of the sheer ability they have to show low dps as that could lead to a person being kicked. Parsers don't take into account gear or movement needed that would affect melee and casters.
