The vast variety of body movement seen in the incredible ragdolling in the game makes me think that war brokers is limiting itself in the ways the bodies move. I think that given the importance of wall jumping in movement that jumping off a vertical surface could be made to look much more distinct that when jumping off a vertical surface. If possible and if done well this might make it more obvious to new players how more experienced players are using the walls to jump.
Now I have no clue how this could be done or what it might look like exactly, but I'm roughly thinking legs angled to the wall side, knees bent and springing the player up.
Maybe a dumb and crazy idea, but just thinking out loud after seeing so many great ragdolls.
