I decided to post this after several weeks of testing so others could try it and test its validity. As a result of Harry's speech where he says " I grow stronger by the minute " a person in one of my pugs suggested that he has more hp the longer he stays in the beams in part 5. He reasoned that if we were to kill the 4 mini bosses faster and get harry on the ground to fight, he might have less hp. I am usually willing to try new things . After all, we had been taking out time in part 5 alot. Going afk, talking, etc..
I began taking the approach from that day since of asking the casters and clerics to use only the sp necessary to kill the first 3 as we corral the last of the four minis and to use the pools quickly, buff on the run, and get down to business asap. I noticed immediate results. Most of our runs are now around the 55-60 minute mark when not crafting and we have had at least 7 runs where someone solo cleric'd. I have done that 3 times and ,yes, I do use a few pots sometimes mass healing in part 4 but that's ok with me. Anyway, I explain this in the many pugs I run and I'm sure it's being used on Thelanis in the runs where people complete it on the square and thought I'd share it on the forums so I could get some feedback.
