After fighting this Boss a few times, Lu Li understood that it wasn't going to be done by today.
He started to try and adjust the team, and kept only Azure Sea Breeze. The rest of the defensive professions were all changed because this Boss didn't require many of them. If they were swapped for Thieves or Mages, this would increase the overall damage output of the whole team.
As for why more healers weren't necessary, it wasn't because there wasn't any pressure on them. In fact, the most difficult part of this Boss was maintaining the team's HP. There was no organisation of healers as there was no point in having more of them.
Loatheb often cast a skill called 'Corrupt Mind' which debuffed all healers after a few seconds. All healing magic and dispels were placed on cooldown for one minute. Within this one minute, only one heal or dispel could be used.
Basically, all healing professions were made redundant – they could only be used at key moments.
