Currently, the dummies you can test rotations/combat on do not work for passive damage. While testing most classes on it works, the Bard passive damage instruments will not function on the dummies, making it difficult to run number tests. Likewise, the Musketeer damage turret will not attack dummies either.
Not that I’m getting ready to run numbers for more Mishka tests or anything 
It’s a little harder running numbers on monsters outside of Highsteppe due to interference from other players, making sure I get numbers at the proper blue bar percentage, aiming crescendos without monsters dodging, etc.
