MTX Chaosborn Druid tame beast skin has no effect

I bought the MTX and tried it with 4 different companions not a single one had any change at all nor any effects at all. The companions I tried were mighty Silverfist, yeti, antlion charger, and quadrilla. Its obvious that this mtx currently doesnt work. Please fix or offer a refund to those that bought it expecting the mtx to actually function.

Same here, $8 and its worthless
