I strongly recommend everyone look over those rules to get a better understanding as to what is expected from all members to insure success and productivity.
Now as for those who still don't know what their role is during Dynamis here is a list outlining various jobs.
What you should be doing...
Melee:
/assist the main tank in your alliance. Stay with your alliance, let the tanks pull. Try to organize SCs with your party and use food. DO NOT RUN UP AND CROWD THE BLMS! DO NOT MELEE STATUES, AVATARS, OR BST PETS! THF keep 2hrs for suicide pulls (If we ask you to suicide you will get raise III) and keep your TH set to MAX.
Tanks:
If you are the main tank for your alliance or party, it is your job to provoke mobs off the main puller and bring them back to your alliance. Be sure to announce in your macro with both /l and /p what mob your taking so the other tanks can grab other mobs. If your not the main tank, still help to keep any mobs provoked off the BLMs. PLDs keep 2hrs for suicide pulls (If we ask you to suicide you will get raise III). YOU CANNOT TANK MONKS! KITE THEM PLSKTHX!!!
Black Mages:
Nuke the statues that the main puller brings. Do not be afraid to be the first to nuke. Kill pets after the BSTs are dead. Keep Avatars slept at all costs! If there are no statues, assist with other mobs. Drain and Aspir are extremely useful. DO NOT USE DoT EVER UNLESS TOLD SPECIFICALLY!
Red Mages:
Silence and sleep BST pets. SLEEP AVATARS!
White Mages:
If only a few people are killed Raise III is appreciated. In the event of a wipe, Raise III for those who de-level if you can, otherwise use whatever raise is available.
Bard:
Lullaby Hecteyes.
