I see people getting around the ilevel requirements for turn 1 a lot. There is one in almost every duty finder pug.
I'm not talking about people doing it to be malicious, they are just being lazy. I'm talking about people with full i90 right side for the wrong class and then maybe the quest af on the left side. Sometimes they didn't bother to get the chest piece and are wearing a pink drop of some kind... (so they don't have all their skills learned probably).
So what this would be is like a healer with all bard accessories for example. As mentioned by the OP, having half i90 gear of the wrong class would mean that you only need i50ish gear for the other half.
Honestly I don't really even care what other people do. I only start looking like if the healer can't keep the tank alive, then I notice they are in half bard gear and go: "Oh..." Besides annoying the group by setting the group up for failure, they are just making things harder on themselves.... "Group Jump Rope" can be more difficult if one jumper isn't going to be able to even jump.
