I'm pretty sure this topic may have been covered before - and I was led to believe this exploit was patched to lead to "insta-death" - but is once again leading to griefers kililng DC players as they exit their alliance base onto the "launch platform" (which should be a safe haven for players until the disembark.
Well... 3 EP players have circumvented this and are using the warden ability to teleport to get themselves onto the platform and grief anyone trying to get through in to the sewers.... anything they can do to gain an advantage they'll do... these events always bring out the worst in people. Video to follow.
