I'm gonna say something unpopular: I don't like to rush.

First: I tank. A lot. I have no problem pulling wall to wall if the healer/dps can handle it. I know my defensive rotations and how to group/LOS a pack so they're easier to AOE. When I queue DF first thing I ask if my team is randoms is "big or small pulls?". I do what people feel like doing because it's easy for me and what I am ready to do when I queue. I also heal and dps so I'm familiar with the dynamic from any particular role.

I have a question to tanks that say they can't do more than one pack. How do you know you can't handle more than one pack?

Honestly nobody owes their party an explanation for their limitations. The expectation is that you play to the best of your abilities and the content gets cleared. Anyone who wants to login and have their fun is welcome to do so. This being said if you want to go slow and your party does not, this is a valid kick/drop reason. Don't ask, don't tell, just play.
I've had hundreds of "oh.. well these guys don't know how to do this" moments where I'll offer help and then be refused or scolded. This is fine, I made the offer at least. If I have a huge problem I can leave. It's a game though and nobody really owes me an "optimal" experience.



Telling someone "well it's an extra skill or two" is judging them on your standards. For many people just dealing with rotation is max capacity. Barely managing a 3 pack when you aren't comfortable positioning for AOE's or are limited by your own capabilities to one hotbar is some peoples normal and should not be taken beyond "can you pull more?" "No, sorry."

The other side of that is you need to understand a LOT of people will drop you from their parties and you shouldn't be salty about it.

I'd like to know if there are any other reasons that genuinely boil down to a player's skill, and not something that can be easily fixed by simple adjustments or pressing an extra button.

I understand your post is from a place of wanting to understand and I hope someone answers so you do. However trying to "fix" people is a little narcissistic. I don't think making others play like you should be the goal. At best you should just be trying to find people who already play like you and stick with them.
