Decided to do a GF run on my Operative healer and got Boarding Party. In the beginning we had to wait for a bit until the other group members zoned in, so I took a look at the Juggernaut tank. His armor seemed suspicious because it resembled light armor. When I inspected him I saw that his gear was indeed a mixture of all armor classes and stats.
I considered telling him what gear worked best for his class, but by then the other group members had finally arrived and we engaged the enemies.
Unsurprisingly, the tank rolled need on each and every piece of gear. The only thing he said throughout the entire flash point was skip despite being called out on his gear and on constantly rolling need.
Furthermore, he kept tunnelvisioning so I and the Sorc DPS got attacked quite often. He also killed the bonus boss Engineer before his droids (luckily I managed to hide behind a reactor core, so it wasn't a complete wipe).
None of the other team members ever bothered using their interrupts. I will never understand why I as the healer always have to switch targets to use my interrupt when three people already have the guy as their target. But then again, I'm the one who would have to heal through it...
By the time we reached the final boss the Sorc DPS had left and the tank and the Assassin DPS managed to pick the guy with the reflector shield as their primary target... While I was healing myself through the damage of the other two enemies - of course the tank didn't care at all - I figured the Sorc had been right in dropping group.
