I hate Kaon with an absolute passion. I run it once a week for the weekly and with guildies. Both the other Mara and myself spec to Rage and the Jugg tanks in rage. We just smash away in the middle. They all die at the same time. Doesn't really matter. I know this isn't really what the OP was talking about but I figured we could just throw the simplest version out there
I get Kaon at least half the time I queue up these days. I've killed them in every order possible using all kinds of 'strategies', including just grouping in the middle and aoe'ing everything to death, which is the simplest way to handle this fight.
The only thing that matters is to agree on the plan and communicate with your group rather than act like a bunch of idiots and spread out all over the room trying to do your own thing.
