Speed hacks?

Q u o t e:
Just want to check I've done the right thing, was just in a match of warsong gulch, and a guy there had some kind of speed hack/cheat (was very obvious, to everyone in the game)

Is opening a ticket to report him, and the situation the right way to deal with it?

I've not seen anything like this before, so am unsure =)

Yup, absolutely! We very much appreciate reports of this nature, and it's best to include the name and realm of a character you report that way. If you wish, you can also report exploitation via the webform here too:

When you use this site, you can select World of Warcraft in the first drop down menu, then Hacks, Cheats & Exploits from the second drop down, then continue to select categories from the drop downs that appear appropriately.
