In my experience the asteroid belt boss in hammer station is more forgiving to lesser gear. I ran it once on my tank with 2 DPS geared for the content. Other groups would have given up, but we advised each other and managed to defeat it, after the engage (tank saved theircooldown, adding a dozen of second of DPS)
That boss is usually hard when healers make it hard. If they position themselves so they avoid the stuns, healing is pretty much trivial. Unfortunately, most of the time they just eat the stun every chance they have.
