New wave? Ever wonder why you wait for tanks / healers or why there is a reward for tanking coil/primals? It's because of the abuse that gets thrown at you for the increased visibility of your mistakes. This is why parsers matter.
When you outgear the fight by up to 40 ilvls and struggle with it killing it or meeting DPS checks, the party deserves to know which poetics princess is holding them back. Pony farming is miserable enough as it is and T9-13 having timed add phases that pad the fight's time length make farming those tiring even with a good group. When the tanks (or healers) are outparsing you, the party has a right to know.
