Why do people bother dodging aoe during trash pulls?

Some people's idea of having fun is competition and rankings. I have never seen anyone kicked from casual content for damage specifically. Usually its for stuff like not AoEing trash pulls.

I understand some people have fun with it but with the amount of people I've seen that try push that kind of competitive behavior on those who might not even raid at all is crazy. That is what bothers me.
Healers and DPS pulling in 24-man raids and dungeons just to do more damage or pull everything even tho it's absolutely unnecessary and showing this kind of example to the new players also annoys me.

I disagree with kicking anyone for anything other than long afk, offline or trolling. Let people play the way they want or just politely ask them why they don't do this or that.
As I said in another post - someone was ready to kick me for single pulls as a tank which is not okay.

Perhaps it's you who hasn't considered you're in the minority. If three other people want to go fast, you insisting otherwise—regardless of your role—may cause friction. And they may opt to kick you. Conversely, if three people want to take the scenic route and enjoy exploring while someone else tries to force a speedrun, they have just as much right to boot them. It typically comes down majority rule.

Nevertheless, Shadowbringers dungeons offered you an alternative though: Trusts. They're more or less designed for people who prefer taking their time.

As for your HP. Seriously, don't concern yourself with your HP. Within reason, of course. It only really matters to the healer.

Considering that more and more people pick up this whole speedrunning mindset it's no wonder people like me are a minority.
But the thing is, going slow will makes someone bored at best. Going fast, on the other hand, will probably make someone stressed, especially if they are a tank or a healer. Which is better - being bored or stressed?
I'd rather people just communicate beforehand.

Unfortunately, not everything can be solved with Trusts. This was a Leveling Roulette run.

And I just can't not concern myself with my HP as I just don't want to die and start this pull all over again. And this adds to the stress, especially since there is just no way out of this pull once it's done. At some point I just run out of CDs and panic even more.
This is a big reason why I rarely do Leveling Roulette as a tank or a healer. While I enjoy tanking and main a healer this is not kind of tanking or healing I want.
People just never think about the fact that someone in a group might feel more than uncomfortable. Like I said above - would be nice for people to communicate, which, to be fair, does happen and I'm grateful to those that actually ask about big pulls before starting.
