Yeah, there are a few cheaters kicking around still. Ones I've reported months ago. Teleporters usually. But I'm used to it, sadly.
But a lot of things ppl are claiming in this thread that are cheats just don't(thankfully)exist in GW2. Like "one shot cheats". I've never seen that. Or cheats that can make you not use any initiative as a thief?...I've never seen or heard of those.
The hacks today that you'll see are usually the typical ones that have always been around like noclip, speed, tele to a certain spot, tele to coords, zoom, esp and pvp and wvw combat bots(these are the newest but still been around for a while). The other stuff I suspect it's just that they were better than you right then. Simple as. Not meaning to sound mean or anything here btw. It's just that GW2 isn't big enough for any competent scripters to make the cheats like mentioned. Plus, there would be vids of them out there on YT and there just aren't. Or go see if you can see if they exist.
