I was more thinking along the lines of Blinking up the scaffolding of the Clocktower in sPvP.
You can blink from a side objective (not from the road but from a roof/wall) straight to the balcony if you target properly. You avoid the whole staircase like this. The more angled the teleport the bigger the chance you will have LoS issues. So try to find a mild angle.
Edit- AH! And never try to teleport deep in the balcony. Always teleport at its edge. It works like a charm.
