In all fairness, the fact that you keep claiming that the healer forums are an echo chamber shows that you are also engaging in some amount of bad faith. The healer forums have a healthy amount of disagreement among the people who post here, the only thing we all are unified on is that the healer role is currently unsatisfying to play.

Look at the DPS forums. The SAM mains are full of a diverse set of players who don't always agree, but they are unified in wanting Kaiten back, would you consider them an echo chamber? The RDM mains also don't always agree, they have people who want RDM to go in completely different directions, yet they're all unified in saying RDM's damage is too low, would you consider them an echo chamber? If you're adamant that the healer forums are an echo chamber despite us disagreeing with each other on a wide variety of things, then you should also consider the DPS forums an echo chamber.
