I disagree with using transpose on a routine basis. In fact you should save it for that moment you screw up or crit a flare or two. The truly best way to maximize your DPS is to learn the fight. Know when and how far to move. If you are constantly readjusting without being forced to or running too far and back you are wasting time. Take Shiva for instance, on the very first AOE in sword form how many ppl do you see moving? 2 or 3 right? There's no need. Your healers can/should be able to handle a minor heal and you should keep casting & take the hit. Simple adjustment in mechanics can easily raise your DPS output 50 points. I never rely on RNG and neither do end game raiders. This is why people do a 5 minute run with BLMs on a striking dummy to gauge TOTAL DPS output. My standard rotation for single target boss: Thunder II, Fire III, Fire I (to 350ish MP; fight determines when I cast next ability) Blizzard III Thunder II rinse repeat.
