For paragons he will be using PE for burn phases, giving haste more power implicitly, something not taken into account for Simcraft. Additionally, during his prog process of Garrosh he will likely be able to become itemized correctly and safely go into a full haste build for that. I considered these variables before giving him my recommendation.
I'll say this again from my first post, theoreticals (Simcraft) are fine and all, but you have to adjust based on fight requirements. I speak from experience and rely less on theoreticals.
