Walljumping is an art in the game and a great way for many people to spend their time in WoW. It's always exciting to climb the next hill up to the last.
With patch 2.4, Blizzard removed that Walljumping, because some players were using it to get in front in the battlegrounds. It's not fair to take away a whole art like that. Walljumping is the main reason for many players to continue playing this game and having it removed, Blizzard IS going to lose a large number of players.
There is nothing illegal in it, it's not a cheat, it's not a hack - it's an art and it shouldn't be removed.
I am myself a great fan and I can say, a skilled walljumper, and this was like a slap in the face for me. I really hope that Blizzard are going to reconsider their decision to remove it.
So here is a Tribute to the art of Walljumping !

Programs used: Sony Vegas 4 (very old) , Virtual Dub

And ALWAYS remember! - Never let the walljumpers fall !.
