So, I was in PvP as EP, fighting with AD in Sejanus Outpost (If I remember correctly). We were crushing main door, when one yellow guy just came out. I used ambush ability to stop him before he get into the castle again, but he did and I pass through locked gate while jumping on him and stuck inside their castle, killed in two seconds.
If everyone use this ambush ability in the same time when enemy is entering the castle, then there's no need to destroy the door (of course not many people play as stamblade these days).
Campaign is called "Kyne", and my character is named "Wuleen-Ze". I don't know If my voice is important, but I just wanted to post this glitch.
