Tried it with three geared out guildies last night along with my ungeared Sentinel self. I just got demolished over and over. I would run to the sides during the Bulwark burst, but it seemed like after the burst channel was done and the animation finished there was still a delayed hit. It also seemed like there was another invisible AOE that happened even positioned behind him. I would interrupt his bulwark smash but that wasn't hurting me. Any suggestions from those who have run with undergeared marauders and sentinels?
do some dailys and get some gear??
