Right now there are some credos with skills/attributes buff. I think there should be something another more unique. Anyway, some day you will get these bonuses, they are not so big.
For example:
Instead +20 MM for hunter credo there could be a chance to oneshot not big animals (would be inbalance to kill trolls/mammonts in one shot).
Tailor instead of sewing bonuses can get ability to craft some unique clothes, probably new gildings/curiosities.
etc.
While it can be hard to change now (and probably unfair for noobs), consider such things in new credos or rework existing in next world.
