Q:
Question Regarding "Void Jumping"
“Breaking out of an map is not something we would normally ban for unless it was being maliciously used. That being said, some breakouts require useage of a bug to perform them and may look overly suspicious to a GM that may be trailing you. I’ll look into it.”
It is not against the rules unless you are using 3rd party software or hacks to do so. Further, it would be against the rules if you use the map break out to be malicious against other players in any way.
As such, if you are trying to break out of a WvW map, I would not risk it, as that will have the most likely suspicion of being malicious to other players (especially with a known “WvW hacker” on the loose).
