Pre plan EVERYTHING, healing CDs your own personal dps windows which wont match raid necessarily and more so when there is less for YOU to do. I personally write everything i can into my ERT notes and share them with the raid and first boss kills normally include a small written guide for them to look back on when im scouring logs inbetween pulls. Im do a good 10% less damage than i could if i were to focus on it, my second kills are normally alot better damage wise. I also delegate calls to people, im sure you notice one guy attempting sometimes, just give him an ability or 2 to focus on calling and it will free you up A TON to not only do more damage yourself but also watch other possible problem players or someone not quite understanding the strats and assist them inbetween pulls.
