Is Grimm worth it for Warriors?

[Sharif Bhuiyan]

Hi guys just wondering if Grimm is worth buying for an endgame warrior or should I just save my plats. I missed Slag's sale so I am not sure how long I have to wait before I can get Slag again so I am trying to get another mythic pet in the mean time (done have enough gold to buy in AH). Any other mythics that worth buying. Already have Abbadon

Grimm is the second if not best pet among the mythic type to have on a war.
And the war class is the best among the three to get a grimm on.
