It's simple to spot commandos. But gosh darn I agree.
I was tanking battle of rishi(on hard). We wiped on the first boss in 30s because "healer" was really a DPS. When I voted for kick it turned out that he queued with 2 DPS and that he 'had' to queue as healer or group finder wouldn't let them. I told him that he didn't had to do anything and I left.
The second time I've encountered commando in armor pierce stance I asked him to switch to healing spec and waited for him to do so. He didn't, I've never even gotten an answer from him and the other 2 people in the party berated me for waiting and I left.
Also regarding DPS behaviour. I've just came back to the game after 2(?) years of absence, hit 65, bought 208 tank gear and the first thing I've noticed is that people don't give a s**** about kill order. I have to run from one ranged mob to the other to stop them from annihilating the healer while also keeping golds from DPS which are relentlessly pounding it. And they refuse to listen or even acknowledge when I ask them to burn weaker mobs first.
As someone said in this thread earlier. There are 2 cultures of kill order. And most DPS are following the wrong one
Hell I could also mention complete lack of CC understanding but I'm easily agitated.
