It seems you insist we didn't listen to you while we didn't really understand the problem you're having, so I propose a solution so we'll reach the same page of your purpose of this thread.

You should record a session of your dungeon run and point out which is the problem you would like to change?
Because I'm wondering why you want to always be moving. (In my feeling, the monsters/bosses stay still at the tank anyway so we can freely shoot without moving)
