Disturbing trend with tanks

[Shalan]

**Edit**
Looks like people are seeing it a lot with healers (and maybe DPS?) too, if I could edit the title I would to players but I can't. Sorry.

The last week I've been working on leveling up some DPS classes and I've noticed a trend that I haven't seen before. Tanks are constantly bailing on my groups before or right after the spawn gates drop without a word, and half the time after that a tank that joins via in-progress will bail as well. This sometimes causes other group members to drop as they'd rather start a new queue than hope we get a tank with "in progress" on and is willing to stick around.

Today alone this has happened seven (7!) times and it's just making the DPS queues that are already long even more painful as once you finally get a group you have crucial party members dropping like flies. I can sometimes semi-tank some of the content with a good healer (playing Ninja) but that can only get you so far.

Did something happen this last week that's causing this or something? Patch draw back players who aren't willing to play dungeons they don't like? I don't think it's the dungeons as I'm seeing this trend all the way from Sastasha up to Stone Vigil
