Early on in gaming I never really liked percentile rolls. I didn't really like percentile based systems. I liked die rolling with gimmicks. For some reason in my mind percentile rolls seemed very bland to me.
In the course of game design (home brew) I sat down and started applying chances of success based on skill rolls and combat. Looking at average percentages for success.
I caught myself doing it a lot with d20 games. Calculating percentage to succeed, making every +1 to hit a 5% bonus in my head.
Now I see that a lot of die rolling is just that. A gimmick. They can be fun gimmicks involving funny shaped die or combinations of die. But in the end its just a statistic for gauging success. This doesn't mean I don't enjoy dice gimmicks. I now have a new appreciation for percentiles as a simple to the point type of rolling.
