Recycled arguments deserve recycled refutations.
But feel free to ignore the evidence, the logs, posted by healer mains showing that they spend 60%+ of their time casting Glare/Broil/Malefic/Dosis in Savage, and consequently, that healers spend even more time wearing out the 1 key on their keyboards in everything below Savage. And go ahead and ignore the videos of P1S and P2S being cleared without any healers at all. And dismiss the facts that healers used to be more complex, and have less downtime, in ARR and HW, and have been considerably and continually simplified and dumbed down every expansion since.
After all, that might get in the way of the fun of knocking down ignorant strawman versions of healer arguments.
