Yeah unless you are knocking that straggler caster mob into the pack because the tank didn't figure out how to get them all in the pull, just don't use the skill.

I'm leveling machinist and the desire to use it is very real as it is part of our dps rotations (on immune bosses) but for regular mobs I must resist. If I do it by accident, I'll say as much in chat b/c I know it's annoying.
