Feel free to move this and the above post to a new thread as it is a derail of sorts.........
The whole weakness thing is not style dependant.
Here is an example
My Monk can use boundless fist on a mob, using that creates a "Enraged" state on the Mob. My groupmate Mr. Rogue detects this and he knows that any time a mob is enraged his backstabs do more damage. So he then stabs the poor sod in the back for a gazillion points of damage. This of course creates a "Staggered" state on the mob which then take advantage of with Crescent Kick so its my turn to deal extra damage....etc etc.
To me its almost a mini game to work within your group to figure out the best chain of events to maximize your damage.
Here is an old post form the VG forums its not complete but you should get the idea.
