As stated in thread title. If it's doable with WSE make it impossible to draw a bow when jumping, interrupts if already drawn. I'd bring up realism, but it's never been important when considering balance in cRPG, so I'll just say it looks completely fucking retarded when archers run away, draw their bows while running, then jump, do a 180° turn in midair and fire. If I wanted to bring up realism I'd say archers shouldn't even be able to draw their bows while sidestepping, moving forwards or backwards, but that would be a gigantic nerf.
Sadly this might encourage even more roofcamping, but archers are mostly light armored and high athletics in the first place. They can already run away fine. They don't need the ability to kite infantry like they're fucking MMO mobs.
