Was looking forward to the new phase diving mechanic and have been really enjoying the patch so far but oh my god did they drop the ball with phase diving, im getting horrific flashbacks to the maw since you cannot mount up at all when in phase diving, not even a ground mount.
You get a a little bit of a speed buff but nothing compared to a ground mount. In my opinion this is a terrible decision, absolutely terrible and is spoiling an otherwise good patch.
