I wasn't paying attention much during the Mountain Lily days, but alright, I didn't know they fixed it, let's hope it's a 100% on these ones. Thanks for clarifying!


Personal stats on raid bosses so far:

Discoverer of a ?-3 raid boss = 17 silver
Participation on that raid boss = 50 silver

Discoverer of a ?-4 raid boss = 22 silver
Participation on that raid boss = 66 silver

Discoverer of a lvl 76 raid boss = 28 silver
Participation on that raid boss = 85 silver

Participation on a lvl 66 raid boss = 75 silver
Participation on a lvl 30 raid boss = 39 silver

Discovering a raid boss seems to give around 33% of participation, as Zandel said. Also, a <40 raid boss gives about half the silver of a >40 raid boss, so ignoring those under lvl 40 is indeed good advice.
