We Need to Start Expecting Mid-Level Sprouts to Play Better

[Duskane]

You make it sound like our expectations are exceedingly impossible, but again...we just want them to use mitigations. And I encounter these tanks way too often for it to be a "non-issue".

what's the solution then, not like they can police people who don't use mitigation and even if tutorial are forced doesn't mean people will pay attention to it.

True, you can't report people who don't use their skills and would be ridiculous to make that into a rule. But you can report those that get hostile towards you for speaking up, or end up griefing you by running into the next wall-to-wall pull and then do nothing and take all the aoes.
The best thing to do is to ask them to use mitigations, and hope they listen. Maybe speaking up about this issue will get more people aware of this issue and change things, but that's a long shot.
