So, I had a very unpleasant experience in game about an hour ago.
I've been primarily a casual player and a mount collector for a long time, but I managed to gear up to 470ish with the help of my high end friends, and I just recently started doing Mythic Jaina runs for the 2x chance at the water elemental.
This week I joined a group mid way, and on the first pull a party member got himself instantly frozen. I was the only one trying to unfreeze him as everyone was clumping on top of the boss instead of having the usual melee/ranged groups (neither strategy was assigned at the start, people simply decided to stand in melee and the ones who were left had to follow). Due to the clumping, the middle of the ship quickly filled up with bombs, and people were freezing themselves left and right, so we wiped in the first phase. Lots of things going wrong there.
The tank leader immediately kicked the one paladin who was frozen first and I made the mistake of standing up for him, because to the best of my knowledge there had been no pull timer, therefore missing out the few seconds until freeze was forgivable (and there were a lot of other problems on top of that). Because I said that, the leader instantly kicked me as well - apparently (he didn't say), he was using a DBM pull timer, only visible to those using the addon. I haven't been using DBM or many other addons since WoD, and I could play at an acceptable level without it (including mage tower in Legion). To be fair, I had completely forgotten it existed. Certainly it wouldn't have been a problem at Jaina, since the biggest challenge was following the marked tank, and the broadsides have visual cues in the standard UI.
To me, getting kicked (and losing my chance at the mount this week) because I tried to stand up for a fellow party member felt exceedingly cancerous. Maybe it affected me more than it would others because I don't usually descend in the septic tank that is pugging difficult content (or multi-player difficult content in general), so I want to know what other posters think. Is this normal behavior? Do you think the party leader was in the right? Or is this part of the cancer that is making wow fail as a social game? (I should probably mention that I was in no way disrespectful or pushy when defending the frozen party member, I merely pointed something out in a factual way - it was a very low bar for "questioning his decision").
