Additionally, when dismounting into combat, my pet isn't even available and there is nothing that I can do to enable it until the fight is over. This, to me, is not what was intended by this change so I'd consider it a significant bug. Pet swap doesn't appear to be an issue when I toggle to druid, but then I can't do that in combat either. Like you, I will probably end up switching my main which is really unfortunate as I mained ranger in GW1 and throughout all of GW2 to this point.
