Just a general rule of thumb...as a dps, you should avoid the front of the boss and where the tanks are standing because not only do some bosses cleave, but because you are also lowering your own damage in doing so. If you need to slow down for a second to recognize where the tanks are and to take note of where the boss will be turning for a switch, it is worth doing so.

Helps if you aren't sure about a certain method/strategy because this is true for all fights in the game at the moment.
