You know what would be hilarious? If beast master was going to be neutered by placing it into the limited job role...
... and it still didn't have fully controllable pets. XD
They seem to not want pet jobs to be taken all that seriously anymore, so any normal interpretation of beast master may be pretty disappointing
I was actually excited for Beast Master until I looked it up on Wikipedia and saw this is what it looked like, then I lost all interest.

People would still find about 70 different ways to complain about both, the exact same way, but with arguments flipped all around. There is no winning, because you can't appeal to everyone, and some people's main reason for remaining in the game is not because they enjoy it, but because they used to, dont anymore, and refuse to let go and leave, choosing instead to complain about everything, for reasons valid or not.
Pictomancer makes more sense as a limited job to me, just if someone started talking about it randomly to me in context of FFXIV. That said I don't want to take away something some people are excited for.
Not my style and so my main suggestion on that isn't to kill another's, but to add my and potentially even more others via paint mechanic. Where you can collect paints as a side mini content, and this impacts the visuals of your spells- like you could have Asian ink painting style.
I do think SE could have figured out beastmaster, if they have to go look at WoW and GW2's notes and copy their homework. If it's that bad, or .. just improve and figure it out.
Both beastmaster and BLU could be jobs that come with cool extra components but are still able to play in normal content. Like how in WoW you have hundreds of pets to capture (not hundreds of abilities, to be fair, but they do have a couple unique skills between types, families, and such, ability differences that do actually matter, same as GW2).
SE could have also improved their pet code. We keep making excuses for SE on why it can't work :(. In WoW beastmaster spec half your damage can be from your pet. Warlock, depending on spec, also has some fairly significant pet moments.
