Hi. Snake said this is the place to discuss the new public wushu mod (wushu3dome), so here are my thoughts:
Frictionless walls make it much harder to use walls for stunts. Maybe it's closer to original wushu this way, but less fun I'd say. The dome shape seems neat, but the frictionless walls make me like it a lot less than wushu3box or marshu (apparently marshu also has frictionless walls, but it was somehow less noticeable because of the very confined space).
Jumping off friction-ed walls may make running away easier, but we already have one public wushu mod with merciless dojo boundaries (wushu_2015) and now the boxed version resembles it more. So yeah, for what it's worth, I liked when walls had friction.
