This is unfortunately true, this community in this game really does idolize the endgame… and subsequently also tries to apply the same “logic” which applies there to pretty much EVERY aspect of the game, including to the basics of leveling and just learning how to play the game.
When it comes to vote-kicking in particular, the sad truth is that many people will just “agree” with the vote-kick automatically and not even look at who is being kicked.
The reasons you were kicked were also suitably trivial, but sadly typical of the current behaviour of what I’ve seen from the WoW community over the past couple years.
If you want somewhere nicer, I would honestly recommend FFXIV at this point.
Is it perfect? No.
But it still is WAY better than the behaviour you see in WoW.
I’ve honestly only seen one vote-kick occur in that game, and the case was most egregious. It involved a tank, in a normally fairly easy two-tank dungeon, somehow managing to wipe the group three times in under 5 minutes at the start of the dungeon on the first pull. I actually had to go AFK for those 5 minutes at the start (and was the other tank in this case), and only found out about it after getting back; pretty much got the run back on track once I joined in.
Now, the other tank was called out for doing a poor job (three wipes in 5 minutes is hard to deny)… but he wasn’t kicked because of that. What did happen, because he was called out, he parked his butt at the entrance in protest; after clearing half the dungeon, we decided to kick him for essentially AFK’ing the entire run.
That’s right, vote-kicks in FFXIV don’t happen because of poor performance.
They happen because you show poor behaviour.
If the group is underperforming as a whole and struggling to clear the content, people are more inclined to “Vote Abandon”; a simple mechanism where if the run appears unsalvageable, a majority vote to call it is passed and the group disbands with no fault placed on any one particular person. This is typically used after repeated wipes only. Some people do leave early on their own accord as well, but again, usually only after several wipes; those who leave after just one wipe are quite rare.
