they did. i tried remapping it to another key but i cant find the walk command in the key config menu. the closest thing to walking without pain in the ass B key is to start walking and press alt. the character will keep walking forward without pressing the B key. nice, huh?
On the pc you can walk by holding the right and left mouse buttons down, but i don't know if there is something like that on the console. (left mouse is activate, right mouse is turn screen)
