Is it an way to end combat with it except leaving house?
Then testing rotations I don't want to go all the way.
Resetting let me get an new dps measure so I can compare.
For some reason it looks like I did half the dps I do on the mini bosses.
not sure exactly what you're asking...It will remain in combat as long as something is 'hitting' it, so if you are a sorc, you have to put away the pet if you don't completely kill the target dummy or it remains in battle. Also all DOTs have to be completed
If you don't want to go all the way, I think you lose some dps as it recognizes you're done, that has been my experience.
Going all the way to killing it, is the most accurate (but time-consuming for many of us!). This is why I think the lower one is probably best for most individual homes vs guild houses.
