Guild Wars 2

We found a really big bug on the map Battle of Kyhlo which gives a huge advantage to the players using it.
During the time before the countdown starts you have to spam jump in front of the wall of your base (whre you start). When the 10 second counter start you useally spawn in your base but with this bug you spawn outside! So you can cap points while others have to wait.

After playing more tournaments we see more players abusing that bug.
