WASD gets you stuck. Not sure if this is the case, but anytime you have it down during transit you're asking for it. You'll port across the screen, find yourself on unclimbable cliffs, be standing on top of an invisible black tower, etc. When someone is just barely stuck in a wall or a weird walkmesh (like the side corners of crypt bridges for example), try backing into them at an angle like you're trying to lever them out of it.
