Quintessence's strategy didn't really work for me. It seemed that every crit means that you you have to start over. I used the other strategy
posted on Xu-Fu's site. Worked on the 1st try so I can't really tell wether or not it is reliable. ...
All in all, and I should say that Q's strategies usually work for me as well, the only issue with some of these strategies, and it doesn't really matter if they are Q's or Gawd's or the Devil's, there are certain things that are tough all around ... and it's like in some cases the stun does not come on round 3 or 4 but on 5, and your adjustment was too early ... as you took the suggestions literally ... and probably did not have Pet Tracker (or equivalent) that shows you which spells the enemy has and is using, and you know when the cool down is over so you can be ready to cover.
As an example, in the Timeless Isle a couple of the Moth's are nearly the same, except that some have this before that, and that before this, and sometimes they are interchangeable, and if you are a "format" player, you're gonna have a hard time. I used Anubis in there to open things (before I learned about the Teroclaw!), and on occasion, you ended up stunned and losing a round, and already took 700 damage and not been able to cast once, because I was set on my strategy, and not what the Moth was doing! A look at the spells and you know that (usually) it is wise to try to stun you, and make you lose a round, before the big hit ... and you do not have a shield ready (always first) you will lose those two rounds and take big damage!
The details, and the wording in the log, is probably too much, even for me, but having something like PT helps some. And the difference in the bigger fights? Yep ... the details, and not just your team, because if you do not use them correctly, your team will also take a dump!
