This is somewhat OT, but the answer to my prob may help him as well. On my 4dk 1hpal team I made a new mapped key I used ~ (oem3 the key before 1 on us keyboards) I bound that to btm lft action bar 1 on my dis and to nothing on my pally. Put deathgrip in that slot for my dks. Set it up as round robin, tar=window current and chose w/o all others for pally (I lead with that one) now for the problem I sometimes have to hit the key 2 or 3 times for it to work even if none are on cooldown
