Staff Fighting Strafing Animation Absent

[FupDup]

So I just rolled a Staff/Ice Brute. The issue is that whenever my weapon is drawn, and I try to strafe using W + D or W + A, then most of the time the usual strafing animation generally won't play like it does with most other sets. Sometimes it strafes normally but most of the time it looks like I'm sliding sideways. If I move purely sideways with just A or D, then the animations work as they normally should. The weapon is currently set to not holster, if that influences the situation. 

 

If I have Ninja Run active, this issue goes away, so I think it's just the default stance where this happens.
