Silencer Plateau

The Silencer Plateau is located in the south-eastern part of Roshamuul and part of the Roshamuul Quest.
When one uses Silencer Resonating Chambers on top of this plateau, Silencers will spawn in waves. 
First wave contains 8 Silencers.
Second wave contains 11 Silencers (to be verified).
Third wave contains 11 Silencers.
Fourth wave contains 15 Silencers.
Fifth wave spawns 3-5 Sights of Surrender at once.
With a well-organised team you can gain huge amounts of experience and loot. However, at least one high level blocker is required as well as multiple shooters, since Sights of Surrender have an immense health pool, often heal for large amounts, and are quite strong against physical damage.
