Best way to see if this is the case is to create an account (here and at warcraft logs), make sure advance combat logging is turned on, log the raid (/combatlog when you enter), and then create a post in the monk section asking for a review.
I seem to be going oom way to fast this time around, I'm using the suggested rotations and its gone by the time trash is done. am I doing something wrong?
Just some general pointers off the top of my head:
•Get at least 30% buffed crit
•Use mana tea during periods of low damage
•Do NOT use mana tea glyph
•Keep renewing mist up in as many targets as possible
•Use your statue
•Use LMG procs for either mana regen (Jab > TP > jab > TP) or free healing
