Today I was doing Mal Prison, GF. They all were level 55 all in different guilds, so I figured it should be a breeze, until the first group, everyone's health just steadily drops. As a tank I instantly though that I did something massively wrong, so I make sure to be extremely aggressive on groups, pulling as much aggro as possible, but their health still drops.
Turns out the shadow was taunting enemies away from me, so I ask him to stop. He agrees. We get to the first boss, and two get one shooted. I finish the boss, pretty much alone, and during the revive process I start looking at there gear. None of them have relics, and those that had implants, ear, and even offhand didn't have any above level 19. I try to explain that relics are good, but someone says "They don't like clicking on them". I explain they can have passive abilities even linking one of mine for example.
In hindsight I should have left, but at least I didn't die on that one.
