Is there way to disable DH defaull attack on mob?

[zevstim]

in higher Rift (35>)

DH dies alot because of damage reflaction champion

I set variable time 30000> on cluster arrow, elemental arrow, multishot

so I don't have to worry that he/she attact demage reflaction champion with skills

but, he/she still uses default attact (none skill attact) on mobs.
