You’ve already replaced healers in casual content.
People go on about savage clears without healers because when people complain about healers being useless in casual content people like you go “casual content doesn’t mean anything come back when savage is done without a healer” then that happens as well and you still deflect
In casual content literally nobody matters but the tank. You don’t need the healer, you don’t need the DPS (though they are at least convenient because they do more damage).
This is a problem across all content that you just refuse to see because you are a tank and so benefit from it. Tanks are the only role that matter right now, everyone is forcibly reliant on the tank in all content with no exceptions unless you want to gimp your DPS and the tank at no point has to rely on anyone but themselves except occasionally needing some DPS to pass savage DPS checks
Put yourself in our shoes. The tank role is so omnipresent in the game as being the most important and babied role in all content and it gets frustrating, especially when tank mains like you come in and go “nah I don’t see a problem”
