Yeah, if you're soft enraging at 28%, there's definitely something amiss with your DPS, especially if all your DPS are as geared as you are.

As many have suggested, learning the nuances of BLM will help immensely. Alternatively, you may wish to have one of the BLMs try SMN as SMN tends to have an easier time with more movement intensive fights. SMN is in a poor spot at the moment, admittedly, but the breath of fresh air may help out immensely - only you'll know if you try that route.
