Nostalrius Begins - Quality wow vanilla realm (1.12)

So, my friend keeps telling me that stealth works differently on the PvP server, than it does on the PvE server. Basically that mobs have a higher chance to detect you. I've done solo runs such as last boss SM for Enchanting Shards, or Solo Diremaul book runs on the PvE server.

He refuses to do such runs because "His stealth gets seen, even by low level mobs" Does anyone know is there really is a bugged differences on both servers? Thanks!

No there shouldn't be. See if one of you are using the improved stealth talent in sub.

Neither of us are using improved Stealth talents.

Well there are some mobs that have stealth detection. E.g. the big protectors in DM. And you have to be extra careful around them. Otherwise the only explanation I could come up with is NE racial or difference in levels, or you just have a better sense of detection range than your friend. ^^
