Goodday!
This post is written from the Alliance point of view in the raid of Battle of Dazaralor.
The last trash pack before the Jadefire Masters (Ma’ra and Anathos respectively), has a beastmaster in it, right in the middle.
Sadly this mob cannot be charged or intervened at.
Tested on heroic, normal and LFR.
I think there is some invis wall blocking my path?
I hope this bug report helps.
