In early WoW speed hacks weren’t detectable. So just using cheat engine I could sprint around as fast as I wanted. Get 10 levels just from exploring xp. Saw all parts of the map that would have taken ages to reach high enough level for. I never took much advantage of it though because I didn’t want my main to get banned. Just fun to mess with occasionally. It didn’t take long to get patched where it would desync and disconnect, making it effectively useless. I tried years later after a long break and it was insta account ban.
