Stop Complaining about a nerf of bitw, the SM was completely broken in terms of exp/gold compared to other shadow missions. Atleast now its more in line with existing shadow missions as it should be.
I am super happy bitw finally got nerfed.
But they didn't nerf if because it needed to be nerfed, or if that was why, they didn't say that, because their reasoning for eliminating the gold rewards at the end was to discourage the usage of alts, specifically alts, as evidenced here.
Blood in the Water changes: Skeleton gold was increased, but end reward gold was eliminated, to discourage usage of alts.
They apparently made it more difficult, increased multi-aggro and added heavystander/naturalshield rats for the benefit of what I assume is a more diverse and functional party.
Similarly, if they wanted to nerf it, then why not just drop the amount of gold and experience you got for each tier? It's just been a general sledgehammer to actual parties for the SM.
