That may seem true, however there are two points to make.
Firstly, Hammer Station can be a tough one because depending on your class and level you may or may not have critical abilities that you would get just one level higher.
Secondly, you may have had a decently geared and decent healer who couldn't keep up because of poor tanking and not enough dps. I was healing Hammer station a couple nights ago and wiped numerous times on the last boss because no matter what, the tank would not turn the boss around... not at the beginning, no at all. A bad tank will wipe a group and it might look like the healer's fault, low dps can wipe a group and it might look like the healer's fault, you might vote kick him and get an really great geared heals who is high level for the FP and he can cover for a lot of failure on the rest on the group.
