Guild Wars 2

I’m on Sorrows Furnace and in the kessix event, I’ve been whitnessing usually a group of four people running in sync usually in an x pattern. When mobs show up, they stop in sync and start attacking.

Now my first thought was they are botting, but having four to five different toons (all dressed the same) attacking in sync and running in sync screams hacking. I reported it and sent in a screen shot but as soon i reported the original 4…5 more showed up. Tried to report them but they keep running around.
