Haha, yeah, that's annoying. My favorite thus far was when I was the only on the team able to make/obtain c5 items. So I was getting swarmed by the enemy while mining the clay, but luckily 4 of my team members, all high level ones, were running towards me! Eagerly I shout out, "Save me! They're going after the clay!" They respond with "no, ill come back in a few secs" So a few minutes later, I died a gruesome death, they got level 5 barricades on the clay, and they got patrols around it so I can't touch it. That's when those 4 guys came back and started demanding class 5 items.
