The problems with Obsidian Sanctum
Well bloodlust bonus used to be applied. They removed that when they added the Arena area for GvG and dueling to make it a even playing field.

I fail to see how these are problems.
It is not what you do, but how and why you do it that counts.
The first point was a bug for sure. I don’t know if it still is.
The second is working as intended. Bloodlust in OS is a bad idea.
