Okay, I understand Stabbey ...
Furter on: this is a
suggestions topic and if I think about making suggestions ... it's for me like
Brainstorming : all what comes in my mind is "maybe" a good or funny idea, no more, no less! Sometimes the seemingly most stupid idea can possible a very nice idea and the fact is that "stupid idea's are the ones that suddenly "plop up in your mind"

'spontaneous (promptings)'
It's up to the devs of Larian Team to gather all the suggestions and see if one of them can fit in their own "program for the next RPG"
I know. But Divinity 2 doesn't give you a huge amount of stat points to play with, you can max out one skill at 100, and a bit in the rest (more if you use the ultimate armor with +30 Str/Int/Dex), and you only run out of uses for your own skill points partway through the expansion.
If they're going to implement stats and skills for a creature, I think a better way to implement stats for your creature might be this: Rather than having the player transfer some of their own precious stat/skill points, a simpler way would be to give the creature it's own base stat pool.
Currently, the creature levels up with you. It could get its own additional stat points when you level up, and a limb selection could also give varying bonuses to certain stats (Dragon Elf gives bonuses to Intelligence, Goblin to Dexterity, the other type to Strength).
As for skills, a creature doesn't need that many, does it? Perhaps it could get one skill point every 5 levels (maybe up to only 8), and you could choose its skills from a limited selection. Heads which currently grant skills could grant bonuses to those skills.
The downside to that is that it would take time and resources to add such an intricate creature system, and it might get annoying for the player to have to manage the creature's stat allocation as well as the players.
