I'm interested in dipping my toes into the system, and have always disliked some of the strictly linear probability of pure d20 -- though to be fair, the quick and efficient resolution of checks in the context of Symbaroum definitely seem like a strength, and I can appreciate the value there. It looks clean in that regard, even as I'm fighting some instincts on coming from a gaming background that favors curved probability distribution.
Open to thoughts.
