I tried to play a Pistol with a Dagger and it really bothered me that when i click onto the enemy my character always runs forward to hit it in melee.
Could there be any option to hit it with ranged attacks until it is in dash range for the melee hit? Pressing shift is an option sure, but it would be far more pleasant if you could choose if you want to hit the enemy in melee or not.
I would suggest that you can pick a "dominant" weapon slot for this combination. So if you have the pistol in the slot your char does not run into the enemies until they are close to you.
