Ok I will give you the spell things fitting into the context, I know I was reaching a bit. But honestly if you dont like how that aspect of the game works, RP and ask somone to stand near the ledge and say help me up and then jump pretending somone was there helping you out.
There are far more pressing issues then being able to jump like a trout heading to spawning grounds. Albiet you have a valid argument and I am not trying to minimize it...much
JK but they will have to redesign alot of things if they changed it.
Heck give us ropes and grappling hooks so I can scale a wall to avoid conflicts or make my own way through a challenge.
