Really needs to be addressed. NBs and DKs being able to do it is bad enough but I've seen at least 3 people on Xbox just straight up crit rushing up the walls.

It is being worked on I can confirm. But as someone said in another post it's something we have to live with. There's a few things that can be done to counter this. Don't stand on the edge of people are near by, have cc and knockdowns at the ready, during defences keep an eye on the mages at the main gate - they are the most abused way of getting onto the walls. If you're a Templar the javelin works wonders and is a good laugh when they die from the fall (also good for taking down people using oil at a breech).

So as said we have to live with it for the time being and adapt to the situation. It's frustrating especially when there is a colluding between your alllies and enemy, most of all try and get evidence and send it via pm to a dev/mod on here.

@ZOS_JessicaFolsom & @ZOS_BrianWheeler are a couple to send them to, Jessica is always on the ball and helpful.
