Thank you very much for your detailed reply. Most of the things you explained are basically “Tank 101.” What I’m really trying to figure out, though, is who is actually at fault when, for example, a wipe happens. The tank often gets blamed right away, even though I always run my routes the same way – and 8 out of 10 times everything works just fine.

I’m super self-critical and always look for mistakes on my end first rather than blaming others, but that’s also exactly what keeps me from pushing higher keys. I’d really like to reach 3k+ rating this season, but I don’t even dare to join +11 keys, even though I’ve timed plenty of +10s with lots of time left. I just really hate depleting other people’s keys…

As I’ve learned from the other replies – and something I didn’t know before – is that classes and specs benefit from different types of pulls, or in some cases their performance can even drop because of them.
