This is by far the worst mechanic I have run into during my time in MMO's. It's broken, it's unfair, it's downright stupid. These stealth detection abilities NPC's have need to be removed or fixed (i.e. range reduced).
I thought the developers were desperate for people to subscribe to the game, silly game design decisions like this only drive people away.
Amazing how annoying

As far as causing people to unsubscribe this is small beans indeed
