So one of the new crafted sets coming with the Necrom expac is the below:

"When you have a living companion, reduce the cooldown of their abilities by x%"
We don't know what the value of x will be. But please, Microsoft, make x% an overpowered, fun number. Like 80%+. I want my companion finally to be useful. I want to see the joy in my pet cat Ember's eyes as she spams Comet non-stop with this set.
