Maybe I’ve been unlucky but players are really toxic in this game

I used to play wow 13-14 years ago, and recently decided to go back to it. Most times when I enter a dungeon I say this explicitly so that everyone knows I might be slow with stuff. However, a lot of times I end up kicked because I’m slower at looting and may be behind my team or get lost when I don’t know where my teammates went. Since i play as a healer, most times tank doesn’t even care to look where I am (like I’m dead and have to walk all my way back at an insanely slow pace) and and pulls whole rooms and dies. The amount of time I had to wait 30 mins cos people kick me just because I may be behind and trying to catch up is unreasonable.

Why so much toxicity? Why not just say in chat if everything is ok rather than just straight out kick? almost none writes in chat in a game that is very much based on team play and I find it quite unwelcoming to the game…

Am I unlucky or is everyone so elitist in this game and pretend you to be the same?

Cheers

EDIT: thanks all for your replies. Now I have a good grasp of what the average player is. Yes it is an elitist community, and yes they expect you to be the same. You’re either like them, or against them apparently. It is not a game where experienced people help newbies (or at least in pugs) and maybe it’s my mistake to think this in the first place. This was my experience in other MMOs, where experienced people take a minute to help newer players cos hell all MMOs would die if you don’t help new players to get engage, cos you need new players. And I thought this game would be no different. But it is, sadly. Now that I know, I will behave accordingly.
