I feel like there should be an option in a platform fighter (not the default settings, mind you) for self-destructs to not take any stocks away. (While still keeping the same percent obviously) Often I have opportunities where I can edgeguard but don't due to me not being really good at it and the risk being way too big, leading to me not practicing it and not getting any better. This could serve as a good way to have "training wheels" for people to practice more risky strategies.
