On the server wow legacy they have released a new world pvp system. (go to http://www.wowlegacy.net/main/?act=idx to learn more)
This might not be an exploit more like common sense.
But this new system opens up a easy way to farm kills. When you join it you will automatically join a raid party. If you go to where everyone is you will get every kill anyone in the raid (thats close to you) does. I went there with a newlt made rogue, stealthed and set follow on a druid healer and went afk for about 1h and when i got back i had 367 kills. :wave:
Hope this counts as an exploit as i try tocontribute as mush as i can :confused:
Just an Add on this system-- When the bg is not on u will teleport into a room that has a blockade infront of the door so you cant get out. Just use the good old fear and you can get anyone out from the room. I think the bosses are spawned and you wont be killd by a horde/ally so its clear to take all areas. (Hope my eng is good enough for you to understand)
