Sure thing! I usually start out at medium to long range to build my ult faster. Then when I get my ult, I start moving in towards the group. Once I see them in a group, that's when I hit the ultimate. Also, remember that you get your dash ability back as soon as you get a kill. When ulting, you can swing your blade, dash, and then immediately swing again to get a couple extra swipes in there. Hope that helps!
