The queen is obnoxious and has to be used in a very specific way to spawn before buffs come out (since it doesn't snapshot raidbuffs, only snapshots your raw stats but with different mainstat modifier, but not resurrection sickness, but it does dynamically update tincture, but not dragon sight, but also not racial stats for some reason, and also not party buff, but it does dynamically update damage down debuffs) and has a stupidly long activation animation, and even though it's under control right now it's very clear it's on the edge of being a broken mess, it also punishes any type of freeplay severely and requires extensive planning for proper use.
You also get none of the benefits of a traditional pet, only negatives. It basically exists in another dimensional realm, no different from dragging a little window with a .gif of a robot spinning and punching invisible monsters on top of the client.
I honestly cannot think of any mmo with good pet AI when involving any type of end-game activity that doesn't involve cheesing, but I do understand the appeal and it's incredibly sad they lobotomized SMN and screwed all those real pet fans for absolutely no good reason, maybe beastmaster will serve as a good testing platform to improve the pet behavior and then it can be applied to full jobs.
