@XaltwindI mean, yes and no. I can't speak for anyone else, but, I can sorta align everyone's actions under the same ideal: Morgan incited a PvP Raid on Chateau Gothika, and a declared War against Bandersnatch. As such, all the Floor Guardians and Facility managers, present, have assembled to do their jobs -- however, with the new ability to deny their Primary Objective of "Defend My Zone". Instead of protocol telling them to protect their Chapter or Facility, they can band together, and confront the issue at the door -- literally.
As to the actions taken to do that, well... Chuunitrixx is an Magical Artillery Battery compressed into Sniper -- nothing about her is quiet, because she was built to nuke positions and players/bosses while hiding in a sniper's nest somewhere. Bone Daddy is a Lv10 Necromancer and Lv15 Skeleton Mage, and is holding a position with magic that isn't subtle by its own dark nature. Mamoru as a Aggro Tank, has a significant presence that she has to maintain, and, most Taunt/Aggro Attacks for a Tank are flashy as fuck.
So, it's less a situation of "why are we doing this this wat," but "we can only do this this way," as we are burdened by our characters and their build.
PS:
@Lucius Cypher, Bone Daddy's Total Level is 50, not 35.
