This is the method we worked out to kill Bulwark, as he was quite tricky compared to the rest of the flashpoint:
There are two buttons to either side of Bulwark. The group should split up and stand by these panels, as far back against the wall as possible. When Bulwark activates his shield mode, it's ok to take your time. Heal everyone up to full, and regen force/heat/etc if required. Then activate both panels to bring down his shield. Later, droids will arrive to repair the panels. Do not kill the droids until they have repaired the panels. He will activate shield again, rinse and repeat.
From time to time, he will target an AOE, which shows as a red targeting reticule on the ground. Run through the boss to the other side. Don't run away, as crossing the closest yellow line on the floor puts you in range of his devastating ranged attack, which will kill anyone in a shot or two.
Tanked Bulwark facing one of the side walls. DPS/Healer stood on the other side of Bulwark.
He will cast "Bulwark Blast" down the center of the hallway. Will one shot anyone down the hall way.
He will cast "Bulwark Smash" this needs to be interrupted by either the tank or dps. This does a knock back and a lot of damage to the primary target.
During the fight he will target members of your party and place a target recital on the ground and shoot missles. This is another high damage ability.
Soon after these abilities Bulwark will cast "Bulwark Shield" this will surround him in a green bubble. You can't attack him. Use this time to regen your resources as Bulwark will not deal any damage or regain any life. On either side of the room there will be clickable control boxes that when clicked will explode. When the two control boxes are destroyed the shield will disappear and you can resume DPS on Bulwark. Later on two astromech droids will appear to repair the shield control boxes. Allow them do perform this function then destroy them.
Rinse and repeat.
