Sometime after Wrothgar was released, I've been noticing I'm able to teleport via the skill ambush beyond an enemy door if they retreat inside. It usually only happens when I'm noticing latency increasing, but I won't say it's exclusive to that, just an observation. I know this has existed for longer, but it's definitely happening more often. I usually ambush when someone tries to retreat off the chance I can stun them and stop them. But I'm just going inside now. That's been sparking people to send me snarky whispers. Usually I just end up getting killed and forced to respawn from the battle, which is annoying. But if I prepared for it, I could easily flag a keep. This really needs to get fixed. My guess is happening more since the LoS changes.
