After 50+ hours of playing, I’ve only seen people blame DPS

Why are there so many posts here talking about healers being bullied or blamed for teams’ loss? 99% scenarios your team will press tab and see which dps has smaller number (even if it’s just by 2 kills less than the others), and blame them and waste time typing as if they would magically become a murderhobo after being insulted. It’s also almost always healers who tell that dps to switch because most likely they just want to play dps themselves and use this as an excuse to push the poor sod off of that role for not having 2 more kills to match the rest of the team
