My entire raid just faced a team that was up on lumber mill using a dragon/pull method to make people fall under the map and d/c. SS of people d/c and leaving the RBG. Reports were made. I have a video too. It has something to do with alter as well.
The evoker uses swoop up (Honor talent that grabs an enemy and drags them to another location.) on a player lets say on an arathi basin at the lumber mill node. the dragon swoops the enemy healer dragging them off the side of the cliff. As they are traveling they clip though the ground on the way. the dragon now uses chrono loop(honor talent that send the target back to where they were when the ability was used on them after 5 seconds) as they pass through the mountain and the healer is ported back inside the mountain after 5 seconds, falling out of the world and spam disconnecting for about 5-10 minutes.
Other arenas work aswell aslong as the swoop clips though a pillar on lets say nagrand, porting the enemy it’s used on inside the pillar and to a spam disconnect. This can be used to great lengths to break the game and needs to be fixed as soon as possible.
These two from first match and then some swapped with the 2nd list:
They are spamming the exploit to boost by D/C healers on opposing team. I hope bliz tanks their rating and issues a ban.
