Detection radius for hostile players is way too small.

I remember it was at last 2 screens big for some time.

But now it was like 1,2 Screens big.

In fact I think I got invaded by Nugiyen?(at last I believe it was nuginuginugi since he was in my wrath instance when I grabbed the support gem) in Coves and I only saw him for 1 second when he was in my screen I popped a QS Flask and didn't see him.

Other example the first Scion in Ancient pyramid.

I got to the top of the Pyramid. Vaal died already and the Scion stood at the exit to sarn and I couldn't see the red cross a bit south of entrance to center to the exit to sarn.
The only way I could realize that Vaal just died was the banished darkness and a whois on the scion which said that he is still at ancient pyramid!
