When fights are mainly locked behind meeting a DPS check, especially in early phases, there has to be SOMETHING, SOMEWHERE, to check DPS/learn a proper rotation. No one will tell you, "doing high on a dummy, is the same as in an actual encounter". However, it will give you the foundation to go forward and attempt to pull similar numbers in an encounter.

If you think adding a parser will add more abuse.. its too late. The abuse arrived ages ago, and will continue regardless of a parser being implemented, or not.
