I started ARR with my keyboard/mouse... but on a laptop it's just not good, even when I plugged in my USB mouse. I ordered an adapter for my XBOX controller like as soon as I knew I was going to be playing this game a lot.

It took getting used to but now that I have my controller it's so much easier for me; I just can't do keyboard/mouse only. (I do have a few shortcuts onscreen that are accessible by mouse but nothing intense like fighting and..moving...)
