I noticed when I purchased a makeover kit for my Asura account that the running animation looked fine unless looking from the front. There is usually a bang with the hairstyle that goes inside the characters skull when running.

The same bug happens on great sword animations as well as bows and dual wielding. I know Arenanet is currently working on more important things however, if this bug ever reaches surface it would be great to have it fixed similar to the Asuras other premium ponytail haircut. I’m not entirely sure if this bug is fixable due to it obviously being a bug with collisions however, I haven’t seen a post in here reporting it. If there is ever a change to physics in the future i thought this would be a good thing to fix.
Thanks Arenanet for making such a great game
