And the healer rescuing you doesn't give a damn for a lot of more important reasons, the first and foremost being it's a casual roulette with pugs who, statistically speaking, eat shit in the spots you're doing that in. They're gonna do what's right from their perspective. Doesn't matter what 'your experience' is. Their job is to keep everyone alive, not just you, and sometimes that Rescue is correct in general in spite of how you 'feel' about it. You can adjust to that by simply telling them you're gonna be greedy during the run ahead of time. Your lack of communication is also a factor in this. But, frankly speaking, your 'uptime' isn't that important in those contexts. It's not their job to make your meaningless normal parse good. But if we pretend this is a common occurrence for you, then, frankly, play better. It IS your job to move into the safe spot in a safe and consistent manner. And you can do that in normal mode without sacrificing any of your precious uptime on every single job. I've done it on every role. It's not hard.
I broke ten thousand hours an expansion ago. Git good. Starting by having some empathy for the literal strangers around you in those pugs.
