Thank you for your reply.
Indeed the issue is DPS output, but I want to know how.
The answer is yes to all except the stim/stance switch which I will employ since both tanks are biochem.
I wish I knew where our loss was, it would be so easy to figure out.
Another thing you could do is video the entire fight, and run MOX at the same time to analyze it more.
Upload the video link here so we can offer more constructive criticism to help you down it.
Parses are very helpful when trying to beat an Ops boss, and it will also help the ones that need to do more dps or heals or whatever.
