Hello dear wow community and blizzard.
We played WSG and the map started and suddenly a alliance allready had a flag caped.So people told it was a speed hack, so we looked an indeed at flag room a death knight runs in with speed like 800% flying around and caped all 3 flags.
I made screenshots so you will be sure and also found his armoy.
Here is hes armory <snip>
And I will add a link where you can see several screenshots
