Shortly after I wrote this initial piece on what I felt was wrong with the Beast Mastery fantasy in Legion, the developers announced that they planned on adding a glyph so that Dire Beast would pull from your own stable of pets rather than use random ones from the wild. This addressed one of the primary concerns, but the other big one was Hati.
Since then, Hati has seen a model update (as seen above) and most Hunters seem to agree that it’s a heck of a lot better than the old model. In addition there are different colors of Hati to match your artifact color. After they did this, I was fairly certain that was it for Hati. Having every single BM Hunter stuck with the same wolf wasn’t ideal, but at least it was a brand new model.
However, in the most recent build a very interesting item was datamined.
