Good for you?
I had several runs ruined because I was getting hit by mobs from the floor below on the last boss.
Several runs ruined from every mob we skipped come running when a mob ran through the wall or we somehow pulled a mob from a floor below.
Several runs ruined from exploding barrels.
Several runs where we had to wait forever for mana because of combat due to cannons.
The season 4 affix did nothing to amend this.
