how i see pld all its ws combos need to be activated from the front point simple. pld is not a dd so their is really no need to be behind or the the sides of a mob, since most likey we are tanking a mob the last thing we wanna do is change the mob positioning and cause an actual dd to miss their combos.

i can agree with few of u guys about the additional effects are done with being on the sides or back of mob. also i would really like to see shield bash along with wardrum included in the combos mainly due to the fact they have little relavent/practical use this will give players a reason to use them more for enimty+ and some dmg.
example phanlax-wardrum-circle slash
example fast blade- flat blade- shield bash
