[2020] Can we talk about the Dark Acorn?

Alright so a quick preface, I think the Hallowed Sepulchre is a fantastic update and with a few mechanical tweaks it will be perfect.

Mechanical issues aside for a second i think we really need to address the elephant in the room, the Dark Acorn. More specifically why does it cost 5000 marks?

I'm fine with the graceful colour costing 1800 for the set but why is the pet recolour equivalent to almost three times the cost of graceful?

For the farming pet at most you're paying 200K for a seed. The golden chinchompa is a test of willpower and rocky will only require berries to recolour so why do i have to spend 60+ hours grinding out 5000 marks for a arguably poor cosmetic recolour?

I really think the Dark acorn needs to be bumped down to 1000-2000 marks, it makes no sense for it to be such a heavy grind when every other skilling pet transmorg is relatively painless.
