I just don't see a reason justifying a full rp bar in the beginning of the match. Idk if people want to see DiVine like performances again. Or.... is that already a thing. I remember a male Turtle in the past doing pretty well without the use of turtle book of course. Pretty sure an old TW players know his name.
Probably not, its just like the fighter's pot. However, spiritists in general need their RP very much. That is why it would be much more prudent than a skill of the spiritualists' primary tree such as "EP energy" changes to give them RP regeneration as a buff, or even direct RP balls "so that the Turtle does not depend on that absurd book and ends with the problems due to the sex of the character. Besides that the Crane would be even more favored by this change.
If this happened. They could block the use of the Turtle Book in PVP and it would be a minimal nerf that any good player would be able to overcome.
