Thats the Shadow Warrior in Assult

Thats in Skirmish

And thats the Swordmaster Enses

As you can see the pet damage is almost non existant. With that damage, the pet is only a tactic holder for 50% more critdamage and 50% Auto attack haste. It might be more sensible to slot Loaner and get the 25% more damage.... might be a higer damage output, although I would have to test it as I had to drop the 50% crit damage.
PS: I hope you can read the numbers. I am not used to do things with screenshots so the chat box may be to tiny. But I am ready to provide more data if someone on destro side wants to meet to produce it.
