What's your statics setup? classes? Guides only work for certain setups and yours might require a different strategy. Also if you have the time, use the DF, I've had some groups get to phase 4, so you gain experience. What you might wanna train as well is placing markers for divebombs, seeing as this is the tank subforum I expect that you tank T9, as your DPS isn't essential it's not a big loss if you spend time marking them, even without getting to phase 4 it's possible to learn this by memorizing.
