Best in Bags seems to give incorrect information for Heart of Darkness

For druid Best in Bags seems to be indicating I should take heart of darkness. This seemed off to me and when I actually run the simulation with each setup it has my original setup at a much higher DPS. IE: 53.4k DPS with current gear, 50.7K DPS with best in bags. The main difference appears to be taking heart over a streaking stars.
I am wondering if it is overvalued for all classes? Just druid? Or will it eventually align with the simulations?
