By comparison to normal scripts, there’s way fewer multi-axis scripts.
Multi-axis is a niche within a niche.
Scripting one axis is already hard and time consuming, so not many script creators get into multi-axis.
You can turn single-axis into multi-axis.
Just this alone gives you more use out of the extra axises.
And even as someone who still more often daily drives their single-axis stroker, straight up multi-axis gets insane and if you’re looking for MORE its worth the upgrade usually.
