As a player who uses a WW in game I can tell you that it does not have godlike range.
A quick glance at terrain, especially if you have ever ganked, gives you a 50-75% accurate guess on enemy location choice.. Lots of good sorcs will drop their aoes in that spot without any form of detect required. Or pop their bird.
People do people things.
A sorc is going be not far off their streak range.
A ganker is already behind you.
A warden is straight line shalks range -not behind the tree.
An experienced ganker is in a totally open area weighing up their choices.
A new player is hard up against the nearest tree or wall, defensive.
If you've played awhile, you know that X player likes to drop from above, or likes the box in Ash wall etc. It's not magic WW nose abilities at play.
A WW has a short detect window. Then it goes where you're likely to be. Then it tries detect again. It does NOT see you from Narnia.
Why is it ALWAYS pvpers that complain about such things and ask for nerfs. This is why eso broke in the first place.
