Overview
How to make your life easier and purge 3 times harder. At least. With less effort.
How?
Very simple, very straightforward.
Use an XBox controller.
I am not kidding, the difference this has made to my playing style cannot be underestimated. The massive difference is the automatic targeting. This makes playing ranged characters several degrees easier, even if you have to get used to the controls again.
This also gives you several excellent sideeffects like for example being able to use a Heavy Bolters spin-up attack and switch between targets without dropping the firerate or being forced to use manual shiftclick aiming all the time.
I realize this is not really much of a guide, but please, try it. And enjoy.

p.s.: Steam is absolutely refusing to let me upload any kind of images, so no art for you. If you like good Adepta Sororitas artwork, check the guy on deviantart anyway.
